This is a simple fix that will make any EA games requiring EA App work

1. Install bottles and install the EA app client using the bottle variant.
2. Click browse files of the EA app client path would be ~/.var/app/com.usebottles.bottles/data/bottles/bottles/{Application name set in bottles}
3. Copy all files from the path above except "bottle.yaml"
4. open path ~/steamapps/compatdata/1222700/pfx and paste all the files from step 2.
5. run the game under PROTON EXPERIMENTAL (ALL games requiring EA APP)

The game runs smoothly however you may find that while playing you won't get any invites. Add your friend first using bottles EA app then INVITE THEM to play with you.
