Boot into desktop mode and select the installer .exe as non steam game. Then install the game or games from within EA App. Once the games are installed you can add their .exes as non steam games also. I think there is a similar process for Epic but alternatively you can install a native app called Heroic Games Launcher which can link to Epic/GOG account to get their games on the deck.i wouldnt mind having the EA App on mine so do i just download the installed and add it as a non steam game? or do i have to install it in desktop mode and then select the .exe as a non steam game?
what about Epic? same process?
