Example project for Image Tracking on visionOS?

I am trying to get image tracking working on visionOS, but the documentation is pretty poor. It does not show how the SwiftUI setup should look like, and also how the reference images can be provided.

For the latter question: I tried to just add a folder to my Assets and use this as the reference image group, but ImageTracker did not find it.
