public class HandMenu : MonoBehaviourRemarks
This class makes the assumption that the tracked offset has the following orientation: When the user's palm is facing down with fingers pointing away from the user, y-axis is up, z-axis is forward, x-axis is right according to OpenXR.
Using controllers you will need different offsets. TODO: Disable GameObject automatically when hand tracking is lost.
