No Occlusion Mesh on Oculus Quest

Has anyone else noticed ```
XRUtils.DrawOcclusionMesh


My capture from RenderDoc shows no glDrawElements occur from inside of the given marker. ![](https://us.v-cdn.net/6024342/uploads/editor/ft/e7kssmz7pab0.png) 

Any info would be greatly appreciated!

I have had correspondence with Oculus that Quest does not implement Occlusion Mesh as Fixed Foveated Rendering covers the same area.
