How to show a video in AR environment using webXR?

I'm playing around with webXR api by following this guide from google, I'm able to render cube and flower as defined in this tutorial to AR world but what I'm trying to do is to render a video stream/video in AR environment using webXR API, while checking for possible solutions I found following links https://discourse.threejs.org/t/videotexture-chromakey-webxr-ar-three-js/16690 but there is no luck in rendering video to AR environment, the video plays actually as I'm able to hear the sound but it is not getting rendered into AR environment using three js.

Can anyone help me with finding a solution for doing so?

Thanks and Regards
