EA app and The Sims 4 with packs bought at Steam

interesting, as I uninstalled Origin and this is the result at some scenarios:
1 - Start The Sims from Steam: No possible, as at launch will ask to install Origin and as you have EA app, will fail
2 - Start from EA app, with Steam loaded: The Sims 4 start as usual, with all packs you bought
3 - Start from EA app, Steam no loaded: The Sims 4 start as usual, no load Steam (I have Tiny home and later bought at Steam) but still can use packs bought at Steam!
