I can't seem to get any hand tracking working in the simulator. And it will fail to launch webXR requesting hand tracking. So I can't test any controls in it. How is it possible to test controls in WebXR ?
Any of these should work

This one is not exactly what you want, but I think you can get some idea. Give it a try.

I have transient-pointer input source fully working now in WebXR in Safari. The controller connects/disconnects within a pinch. so a pinch release disconnects. So its hard to detect raycast and hover effects. selection and raycast happens on selectend event.
