EA App, removing or blocking games

right to start I brought the sims 4 from steam a long time ago for nostalgia but they release add on add on add on, drove me nuts with the amount of junk (should be in the game only or most should have been included) either way I hardly played it as I think its junk, I blocked it in steam so no longer have a issue there ( I don't want to remove from account as iv paid for it ) however now this new EA app has started sending push notifications to the junk and there don't seem to be a way of blocking that one game without removing advertising for all games content advertising for games I own, and the EA app don't seem to have that function the website has no links to contact unless I'm banned apparently plus the bot chat is totally useless don't seem to have any understanding  or of it own functionality programmed in.
