Optional: This field holds the reference to the PoseProvider instance that, if set, will be used to override the behavior of the TrackedPoseDriver. When this field is empty, the TrackedPoseDriver will operate as per usual, with pose data being retrieved from the device or pose settings of the TrackedPoseDriver. When this field is set, the pose data will be provided by the attached PoseProvider. The device or pose fields will be hidden as they are no longer used to control the parent GameObject Transform.
