It only allows me to install the windows version and I'm not sure how to install the apk for Oculus Quest.

Nevermind I figured it out

HI

How did you figure this out?

The apk is not needed anymore. Claim the oculus key on itch.io and redeem your code here : https://secure.oculus.com/redeem-code/
You should then be able to install it directly on your Quest.
