UNNotificationAction 未显示在远程通知中

问：

我正在实施可操作的远程通知，但操作按钮在来时没有显示。notification

有效载荷

{“aps”：{“alert”：“测试.. （11）“，”badge“：1，”sound“：”default“}，”category“：”newnote“}

我的代码

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        self.configureUserNotifications()
        self.registerForRemoteNotification()

        return true
    }


func registerForRemoteNotification() {
    let center  = UNUserNotificationCenter.current()
    center.delegate = self
    center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
    if error == nil{
        UIApplication.shared.registerForRemoteNotifications()
    }
}


func configureUserNotifications() {
        let acceptAction = UNNotificationAction(identifier:
            "accept", title: "✅ Accept note", options: [])
        let rejectAction = UNNotificationAction(identifier:
            "reject", title: "❌ Reject note", options: [])
        let category =
            UNNotificationCategory(identifier: "newnote",
                                   actions: [acceptAction,rejectAction],
                                   intentIdentifiers: [],
                                   options: [])

        UNUserNotificationCenter.current()
            .setNotificationCategories([category])
    }



    func application(_ application: UIApplication,
                     didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("Registration for remote notifications failed")
        print(error.localizedDescription)
    }

    func application(_ application: UIApplication,
                     didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("Registered with device token: \(deviceToken.hexString)")
        self.deviceToken = deviceToken.hexString
    }


    //Called when a notification is delivered to a foreground app.

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("User Info = ",notification.request.content.userInfo)
        completionHandler([.alert, .badge, .sound])
    }

    //Called to let your app know which action was selected by the user for a given notification.

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("User Info = ",response.notification.request.content.userInfo)
        print("Response received for \(response.actionIdentifier)")

        if response.actionIdentifier == "accept" {

        }
        else if response.actionIdentifier == "reject" {
