## Discussion

Discussion In macOS, this icon replaces the default icon of the app. struct MyApp: App {     @State private var isShowingDialog = false

var body: some Scene {         Window(...) {             Button("Delete items") {                 isShowingDialog = true             }         }

AlertScene(             "Are you sure you want to erase these items?",             isPresented: $isShowingDialog         ) {             Button("Erase", role: .destructive) {                 // Handle item deletion.             }             Button("Cancel", role: .cancel) {                 // Handle cancellation             }         }         .dialogIcon(Image(Trash.png))     } }
