I understand that fully immersive experiences, Quicklook using USDZ, and the newly adopted <model> element tag for 3D objects are all supported in WebXR in Safari on Vision OS.
What about Mixed Reality in WebXR? Meaning augmented reality experiences seen using passthrough on the apple vision pro where you can see your environment in combination with the webXR experience. (not fully immersive)
Can you run full webXR experiences in passthrough mode? Or just view 3D models.
