Added the EA app as a non Steam game, installed on GE-Proton10-4, installs correctly and even runs. When Launching Titanfall 2 it logs into the EA app, prepares the game and still won't launch the game. Added Titanfall2.exe as a non Steam game also, it runs but then detects Origin is not installed and closes.

I'm thinking about editing some files to point to the directory where the EA app was installed so it reads it for the DRM, but I don't know which. Hopefully someone smarter than me can figure it out.
