To be fair, I bought the app years ago when that wasn't a thing. But I also don't see webcam as an available option when plugging it into my PC. I have a carrier branded Pixel 8 rn, so it might not have everything a regular stock android would. :/
I can actually just use some FOSS thing I found on GitHub to basically remote access my phone now via ADB, which is also handy in VR as I can use a VR version of it without taking off the headset.
