And now for a real answer is you can use AppIntents. I did that for one of my apps. Just created an Intent and in the title and description areas i just put "Old App Name now (.applicationName). Im able to see my new app as a short cut by searching old app name.

Is there also a way to do this for the virtual camera? For iOS I'm unable to add attachments to the the RealityView. I know I can probably do a ZStack but if for some reason i wanted a swiftUI view on a 3d box i dont see how to do that natively
