Okay I give up. Spent the last hour or so trying to stream games from my PC to a Quest 2 without having to buy something or sign into fucking facebook. 
You guys probably get this a lot here but I'm hitting a dead end in getting this working. 
I currently have sidequest and I can install APKs on the headset, but that's as far as I got. Virtual Desktop needs you to buy it, and Air Link needs your account BS.
