SwiftUI App WindowGroup options for Catalyst?

Can a Catalyst app built with SwiftUI App have a hidden titlebar, or other window titlebar options?

Ie. an iOS app running on macOS built using the App protocol without this error:

ERROR: 'HiddenTitleBarWindowStyle' is unavailable in iOS

Code Block @mainstruct MyApp: App {	var body: some Scene {		WindowGroup {			ContentView()		}		.windowToolbarStyle(HiddenTitleBarWindowStyle())	}

I tried lots of work arounds including trying to use @UIApplicationDelegateAdaptor to get the windowScene (fails)

Code Block windowScene.titlebar?.titleVisibility = .hidden

Anyone have suggestions or workarounds?
