BF6 early Beta access/Steam purchase

Hello gamers and devs, 

Wanted to get some clear confirmation on the BF6 beta early release. I received the code via watching BF6 twitch stream and successfully applied it on my EA account. However, I bought the BF6 $99 preorder on steam. Will I be able to still play the early access beta via steam or will I have to buy the game through EA since that’s where the code was applied too? I saw somewhere where if your steam is linked then it should work. Can any devs / managers / gamers confirm or explain? 

thanks
