Adding Catalyst App to iOS AppStore option

I know with macOS 11 and iOS 14, iOS apps will run on Apple Silicon. I have a Catalyst version of my app, that I would like to add to the same AppStore Connect entry. I know I have to remove my Mac App Store entry, but I can't figure out how to change the App bundle name in the App Store Connect for the the Catalyst app.

Do I have to build a native Mac Version with the same bundle ID as the iOS version to have it on the same App Connect entry?

My app is free and I want people who have it on iOS to have access on macOS.
