Method OnGrabCountChanged
OnGrabCountChanged(XRGrabInteractable, Pose, Vector3)
Called by Unity each time the number of selections changes for the given Interactable while grabbed by at least one Interactor, including when it is first grabbed. Use this to do any code initialization based on each Interactor currently selecting the Interactable, for example computing the initial distance between both Interactors grabbing the object.

Remarks
There will always be at least one Interactor selecting the Interactable when this method is called.
In other words, this will be called when the selection count changes from 0 to 1
and whenever it subsequently changes while still above 0.
This method is called by Unity right before Process(XRGrabInteractable, UpdatePhase, ref Pose, ref Vector3) if the selection count changed.
