On macOS Settings window navigation bar item is in the center

Hi,

Overview

I have a Mac app with a settings window. When I add a button it is added to the center. I want it on the trailing edge, I even tried adding it as confirmationAction but doesn’t work.

Steps to reproduce

1. Run the project on mac
2. Open the app's settings by pressing ⌘ ,
3. Notice that the Save button is in the center instead of the trailing edge

struct SettingsToolbarButtonBugApp: App {

            ContentView()
        }
        
        Settings {
            SettingsView()
                .frame(width: 300, height: 400)
        }

    var body: some View {
        NavigationStack {

            }
            .toolbar {
                ToolbarItem(placement: .confirmationAction) {
                    // Save button is the center instead of trailing edge
                    Button("Save") {}
                }
            }
