Makes an object grabbable by hands so long as it's within arm's reach.
A
HandGrabInteractable indicates the properties about how a hand can
HandGrab an object. It specifies the fingers that must perform the grab and the release and generates the events for the Pointable to move the object. Optionally it can reference a list of differently scaled HandGrabPoses to inform the interactor about the best pose the hand should adopt when grabbing the object with different sized hands.
