User experience for exiting immersive mode isn't great

[jdm]

Some feedback we've received about the current gesture, where there is no indication that you're doing it correctly until the menu appears after several seconds:

 Exit session hand gesture isn’t discoverable. I'll try to see if there are any interaction experts around that have advice or a best practice for this. This is probably a more difficult problem than for single-purpose apps because it is hard or impossible to coordinate with any of the infinite webxr apps that could be running.

Hi, for the exit gesture, I would recommend integrating the animations provided in the "hand coach" -- you could combine the palm up with the near select gesture to simulate the gesture you need to go home.  

I suppose the app should render something indicating "exit" when palm up, then when user "near select" it, exit the app.

currently it is "looking at palm, palm facing you", i've managed to trigger it by accident a lot

Something that might be straightforward to prototype - could we apply a full-frame effect like dimming that intensifies the longer you perform the gesture? The main downside here would be if there's snapping effect if the gesture stops being recognized after 50% of the time; making the effect reverse in an accelerated fashion might be less jarring.

A full frame effect would be easier, yes. We could also draw something on the hand.
