What's the proper way to get pirated VR games working? Adding them as non-steam games and then checking the "Include in VR library" does add them to SteamVR, but then the game never loads when I launch it.

I have to launch the .exe from regular Steam instead, and I have this weird issue with Half Life: Alyx where my game launches on my monitor instead of the Oculus Rift S.

It's a Vrex pack, which is what I've been using for all the other games, but for some reason HL:A is refusing to launch on my headset and I don't know what I'm doing wrong. Should I try reinstalling it?
