Vive Browser not reconizing "immersive-ar" as a valid WebXR session

[Courgeon Matthieu]

Hello, 

I'm trying to use WebXR immersive-ar on the Vive XR elite. My code works well on the Oculus Quest 2 as well as on the Hololens 2

However, on the Vive XR Elite, session mode "immersive-ar" is not found, only "immersive-vr" will work, but then, no video passthrough is available.

Using this page, it does confirm that "immersive-ar" is not supported by Vive Browser.

Is there some option to enable somewhere ? It's really a shame that a headset name "XR" won't allow webXR to render XR content...

Thanks
