Example of VR app made with Unity that runs in a web browser and supports both Oculus Rift and Quest

I have a game at the moment that has no VR code in it, however adding VR functionality would be
fairly easy to do. I’d like to explore using webVR since that would
allow people to play it on both desktop and mobile headsets through a
browser.

Could someone do
me a favor? Find an example of a VR app made with Unity that runs in a
web browser and supports both Oculus Rift and Oculus Quest. If that is
possible, I’d be happy to contribute to a port for the game to work like that.

Thanks!
