Despite what the OP of this thread said, I use proton through Lutris. I haven’t used any other tool for this yet, though I hear heroic games launcher is good too.
I’m not looking at it right now, but on Lutris you can add a new game, say it should run under wine, and then pick one of the versions of wine with proton.
I hate having to break out the scissors just to eat my SD card.
