You'll need an Oculus Quest to run this with experimental hand tracking turned on.

• In your Oculus browser, visit chrome://flags/
• Enable WebXR experiences with joints tracking (#webxr-hands)
• Disable WebXR experiences with hands tracking (#webxr-hands-tracking)
• Enable "Auto Enable Hands or Controllers" (Quest Settings (Gear Icon) -> Device -> Hands and Controllers)
• Use your controllers (not your hand) to press the Enter VR button below.
