How to change UIBarButtonItem tint color based on whether UINavigationBar is showing large or normal (collapesed)?

Setting the appearance of a UINavigationBar title, background, etc. based on whether it is showing large or normal is no problem. But how to update the appearance / tint color of the bar button items accordingly?

Have a code at the following appearance and the code that I used to create it:

enter image description here

UIBarButtonItem.appearance(whenContainedInInstancesOf: [MyCiewController.self]).tintColor = .orange

let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .orange.withAlphaComponent(0.5)
appearance.backgroundEffect = UIBlurEffect(style: .systemChromeMaterialDark)
        
// Set different title colors for large and normal mode
appearance.titleTextAttributes = [.foregroundColor: .white]
appearance.largeTitleTextAttributes = [.foregroundColor: .black]

// No effect
appearance.buttonAppearance.normal.titleTextAttributes = [.foregroundColor: .white]
        
UINavigationBar.appearance(whenContainedInInstancesOf: [MyCiewController.self]).standardAppearance = appearance

So, setting different colors for large and normal title is no problem. However, I did not find any appearance property to do the same for the bar button items. My best guess was to use buttonAppearance but this had no effect.

How to make the "Done" button white in the normal nav bar? Is it possible to use appearances to solve this?
