While this tool is really cool for seeing things, it should not be veritable on an experience except by the creator.
The simple case for this is if you make a game where people might be hiding behind a wall you certainly don't want this capability available for any user to just circumvent the wall.
The FPS display would be acceptable to allow any user to see, but not the rest of it.
Optionally allow the experience owner to set a switch in the scene settings to allow or disallow this viewing of diagnostics info. This is similar to the debug console. This needs to be given the same insight.
