Did you ever figure this out?

More info: I am using Reality Composer pro to create the 3d content, each category with a different transform. The transform is then linked to an Item by name. I then want the RealityView to show any Items in items that have enabled=true. Not sure if their might be a better way to implement this.

Update. I figured out if I can kill the RealityView when I move to lets say the home tab instead of the AR tab, it would have to refresh the entities anyway. What's the best way to pause/kill the view when I move to a different view/tab? (I also noticed that performance takes a hit in other areas if it stays open.)
