Swift Pro - Universal Holder

I couldn’t find instructions anywhere on how to install the universal holder, but I gave it a try by replacing the suction gripper. I plugged the 4-wire cable from the servo into the arm or “wrist” (see attached picture). Is this meant to be controllable by the “Wrist Turn” by uArm studio? Every other control works in the uArm Studio except for the Wrist Turn.
