Questions about GoPro Karma Grip Handle

The Karma Grip is the complete system with gimbal. The Karma Grip Handle is only the handle itself. As far as I can tell, it is an original spare part (listed under accessories at GoPro), either for the gimbal system or the Karma drone, as the handle is already included with both products.
