how do I do that?

I don’t know , you will have to research that yourself 

Yes this is will be good 

Here are a tip to PVZ2.Please help to tell your team Okay?

Bored of penny pursuit and Arena every day. Hopefully add PVZ3 Scrapped Devour Tower to PVZ2 and Carnie own its own music like zcorp and just adjust roman dr.boss and catapult bad animation.Had better change its basketball number from original 7 to 20 like pvz1 because returned catapult zombie is TOO WEAK and lose its vaue if he cannot be henced.And make some thymed limited events like zcorp,roman and carnie become forever open to play like 11 main worlds and hope to have a plant level Switch system because it has no fun to use high levels plants to defeat zombies.And hope add more pvz3 and pvzh plants and zombies to pvz2.

Here are more Detailed music loss issues and some precious advice to pvz2.Please convey them to your team.Music issue:Whenever I click the pause button,world music will restart and some world partly music loss problem has existed for a long time e.g.moderm day since version 10.1 I remember.
Bugs issue and advice for pvz2:
1.please add Marigold back to plant card UI. You can add a "Not belong to any family"logo like not from any worlds.She disappeared since the new plants card UI was introduced.Cleanly this is unfair after all she is also a plant.
And with pvz3 updating,hopefully pvz2 will in the future also add some fun contents from new pvz3 like pvz3 variable watery maps to enrich pvz2,considering that you are adding sea shroom and more aquatic plants to pvz2.
2.The good news is that PVZ2 now allows to choose a 60FPS.Besides,hope and advise PVZ2 can restore into the same slow pace/rate before version 1.7 like puzzle map,considering that PVZ2 levels move so fast, making it tiring to play and lacking the fun of tower defense games.Remember in version 1.7 there is a button to make fast pace to recover into slow game pace.

3.please have a level switching system that allows plants to switch to lev1 or else there is no fun with high plants levels to play the common levels with level 1 zombie.
4.Make game world maps larger as soon as possible in terms of mobile screen adaptation.There is too much distance between the left side of the small cart and the plant card selection box. Namely,make world map to be able to cover almost the entire phone screen like playing pvz2 in iPad or like pvz1.
5.Hopefully, pvz2 return rest of PVZ1 plants and zombies and Dr.boss and bring back some classic plants and zombies from other PVZ series(like PVZ3/PVZ hero/PVZGW/PVZA) and add more New Modes(hope PVZ3 scrapped Devour Tower mode and mode Memory lane like PVZ2 China will be added to PVZ2)as well as pvz2 team can go on making more new worlds and new maps/music after modern world.

6.6.For thymed events,hope special events with unique map like Roman,Zcorp and Carnie can be forever open and will have their own endless level.And make music for Carnie theme and Zombot for Zcorp event and add more wave of bgm for Roman,for Roman event music is not full and only has 2 wave.
7.After plant Gold leaf has a upgrade system and level 1 recharge time becomes longer. it's even worse.Because its recharge time is longer.Since so,what's the existence meaning of this sun plant for 50s recharge time?a level will finish before planting few gold leaf and cause completely cannot get enough sun.Hopefully its recharge time will be shortly e.g.10s for level 1.This way this plant's usage rate will be added.And please make gold leaf,hot potaoto,Perfume-shroom and Thyme Warp the 4 plants can also be used In Any World's Endless level, adjust hot potaoto this plant.Allowing it to melt ice in Level 1 not high lev
8.Catapult zombie's animation is Too Bad,please make adjustments for better and smooth and common players feedback this returning zombie is Too Weak and Kind,hopefully you Strengthen its blood and Add back to lob 20 like PVZ1 to better into PVZ2 environment.Just Lobbing 7🏀 makes this zombie Weaker than PVZ1.

9.Plant Buttercup lacks her "Giggle"sound effect for a long time and some others plants as well.
10.Fix Plant Vamporcini's bug.He should have continued to drain blood again after first draining with time going by but in game he can just drain blood Once so players think this plant is too useless and needs to Change.
11.Especially want Umbrella Leaf and Bungee/Bowling zombie added to PVZ2 depsite having appeared in PVZ3 and considering more aquatic plants are in pvz2,expect pvz2 team can bring back Cattail and Dolphin Rider zombie
12.Somehow using plant Noctarine is still caused some players' phone become out of order.And with more PVZ1 plants returning,hope to divide PVZ1 plants from PVZ2 to find them better.
13.In animation and artstyle and Zombot's making hopefully pvz2dev can do better.And let plant Pumpkin have a function that players can freely decide to remove plants first protected by him or remove pumpkin first like PVZ1 according to the situation.

14.Please draw Returning plants from pvz1 or others Adorable.Most players are especially displeased about scaredy shroom's image.
