Hi! I have an app that's only a MenuBarExtra (no window), and I want it to run a script when the user clicks its icon from the menu bar. Currently I have a button on the menu that, when clicked, runs the script and updates empty, placeholder text fields, but this extra step is less than ideal. class AppState : ObservableObject {   @Published var textToDisplay = "Script has not run" } @main struct MyApp: App {   @StateObject var appState = AppState()       var body: some Scene {     MenuBarExtra("My App", systemImage: "pencil.and.outline") {               // create text bar       Text(appState.textToDisplay)               // create button runs my script       Button("Manually Run Script") {         RunMyScript()         appState.textToDisplay = "Script finished running"       }     }   } How can I have the script run automatically when the menu is opened?
