Attaching Quick release to Cube Controls F-Pro

Hello,
I watched the tutorial video from Simucube for attaching the Quick release to a cube control wheel.
Is it correct that I only have to use 3 screws to attach the wheel and then the 4 screws to mount the backplate as described here https://youtu.be/Jv2h1eTtD0s?si=M4oIJRq_KCUXrOJY at 1m38s?

Kind regards!
