Apple Vision Pro - WebXR VR Lab


I’m attempting to run the WebXR VR Lab (WebXR VR Lab - PLAYCANVAS) on Apple Vision Pro. Initially, it indicates that WebXR is not available. However, after enabling Safari WebXR following these instructions: Enable WebXR support on the Apple Vision Pro, I see the VR button. Unfortunately, clicking it does not enter immersive mode.

Is there a solution to make this work?

Thank you!
