WebVR with the Valve index

[Sekter]

So I am new to VR, I got the index over the past weekend, and I was looking to watch some streaming VR videos..... for science...... and It is telling me to get a web browser that can handle VR support, I did some research and it looks like I need something like WebVR (I guess it might be called WebXR now?), but I did not see a valve index compatible version on the valve store.

So what is the best way to watch streaming VR videos on websites with the Valve index?

Thanks

After some research, I found something called super medium, but it is no longer available. Anyone know a work around?
