Is it possible to add an AppDelegate to an independent watchOS SwiftUI app?

Question

I am trying to add an AppDelegate to a standalone watchOS SwiftUI app (no companion iOS app) as indicated in here, but I can't seem to resolve the issue Cannot find type 'UIApplicationDelegate' in scope

Explicitly adding an import UIKit does not help.

Any clues?

UIApplicationDelegate seems to only work with Catalyst, iOS and TvOS. Per WatchKit documentation it using the WKExtensionDelegate that has all the same methods.
