It seems if you have editing rights, any preview mode in the system still shows a top retool bar and bottom bar. It would be nice if there was a way to get the same view as a viewer-only user where there are no toolbars and the app is fully edge-to-edge. Some of the apps we're developing we also need to use daily, so it would be nice to have the same experience as a view-only user.
