Information About Local Communication with A-painter

I would like to draw with various elements because it can be expanded using VR paint software called A-painter, and since it is possible to develop locally, I am trying to draw on local communication.
However, when you communicate locally, "Access this site over HTTPS to enter VR mode and grant access to the device sensors." If you turn it off and put it in VR state, you will see video playback buttons, zoom bars, and so on.I cannot draw using the controller under this condition, so please let me know if anyone knows how to release it.

I'm sorry that I don't have enough information to ask you.
