struct MGIntents: AppIntent { static var title = LocalizedStringResource("open app") static var openAppWhenRun: Bool = true func perform() async throws -> some IntentResult & ProvidesDialog { return .result(dialog: "app open") } }

struct AppItentsShortcuts:AppShortcutsProvider {

static var appShortcuts: [AppShortcut] {
    AppShortcut(intent: MGIntents(),
                phrases: ["\(.applicationName) Open app"],
                shortTitle: "Open app",
