How to visualize movement that occurred by reaction force with Simscape multibody?

I'm trying to visualize manipulator that mounted on satellite, so I made simple shape.

At Simulink, I set uniform gravity as 'none' to implement zero gravity.

So I thought that when manipulator is moving, satellite(gray cube) will move slightly because of reaction force, but it's not moved.

How can I visualize movement of cube that occurred by reaction force at zero gravity?

The grey cube should move if it is not fixed and connected to the arm through a revolute joint. The motion maybe too small for you to see. Connect a sensor block to the cuebe to measure the movement.
