AR Passthrough / ZED Unity Package v3.5 / Unity 2021.1 / XR Plugin

Anyone have this combination working? Maybe I could get a copy of your Unity project?

If I use the Zed_Stereo_Rig prefab, it works, but I get strange rotations on the pass-through quads in the Rift.

There's no updated documentation on GitHub (unity package) or Stereolabs developer for the new Unity package. I have posted on the Stereolabs Community forums, but no responses.
