I tried several methods already. The last one did let me actually make a screenshots, but then SwiftUI seems to confuse itself and stops showing me the AR video capture and my other SceneNodes. Just white. Toolbar and other SwiftUI stuff is still showing as intended.
So here is my question:
What is the proper way to take a screenshot of a running ARKit session in SwiftUI?
Keep in mind, I don't need the captured video image, I know how to extract that.
