Hi @cloudxxx8 based on what we've discussed last time( we don't the camera-control-device-service), I think we can remove this entire walkthrough as we have the existing camera-related walkthrough on the docs. This walkthrough is mainly focused on the camera detection. Also, we have the virtual device service walkthrough already.
