I'm not familiar with the Quest, but from reading online it looks like you need to 1) link it to your PC with a link cable or AirLink, 2) Open the Quest app from your PC and change the settings to allow Link, then 3) Open the browser from inside the Quest app and open the game. It might require permission because it's a 3rd party game. This website has more, better information: https://www.thegamer.com/play-pc-vr-games-meta-quest3/
