When will the DrawHiddenAreaMesh_RenderThread method under IHeadMountedDisplay.h be called?

This method was overwritten in Oculus’s code, but the test was not called in OculusGo.
I have also rewritten this method myself and have not called it. Is it only available on PC?
Is the HasHiddenAreaMesh method bound to the hardware?
Is there another configuration item that controls the opening of this part?
