How to display spatial images or videos on swiftUI view

Hi! Now I am making a visionOS program. I have an idea that I want to embed spatial videos or pictures into my UI, but now I have encountered problems and have no way to implement my idea. I have tried the following work:

1. Use AVPlayerViewController to play a spatial video, but it is only display spatial video when modalPresentationStyle =.fullscreen. Once embedded in swiftUI's view, it shows it as a normal 2D image.
2. The method of https://developer.apple.com/forums/thread/733813 I also tried, using a shadergraph to realize the function of the spatial images displaying, but the material can only be attached on the entity, I don't know how to make it show up in view.
3. I also tried to use CAMetalLayer to implement this function and write a custom shader to display spatial images, but I couldn't find a function like unity_StereoEyeIndex in unity to render binocular switching.

Does anyone have a good solution to my problem? Thank you!
