Support for Shadertoy?

[Boscop]

Thanks for this extension :) Any idea why this extension doesn't work on Shadertoy with VR shaders? E.g. if I go to https://www.shadertoy.com/view/llj3Rz and click on the VR button, it says

WebVR API is not supported in this browser

But it works on this site: https://webvr.info/samples/05-room-scale.html

It might have to do with this line in Shadertoy's source code... 🤷‍♂️
