Apple Watch Notification Actions not working when iPhone companion app is terminated watch OS 5.3.2

I am working on iOS app which is supported watch as well below is my concerns.

watch os - 5.3.2 and iOS 13.1

I am facing problem with notification actions in watch app. when iPhone app is terminated and if I get a notification in watch , if I tap on action nothing happens.

I am relaying on push notification and for user notification actions I am registering for user notification.

as below

// this I will call in iPhone app code in did finishlaunching with options.
  func registerForPushNotifications(withUserInfo userInfo: [AnyHashable: Any]?) {
  if #available(iOS 10.0, *) {
  self.requestAuthorization(withUserInfo: userInfo)
  } else {
  registerUserNotificationSettings(withUserInfo: userInfo)
  UIApplication.shared.registerForRemoteNotifications()
  }
  }
  func registerUserNotificationSettings() {
  let approveAction = UIMutableUserNotificationAction()
  approveAction.title = NSLocalizedString("Approve", comment: "Notification approve button title")
  approveAction.identifier = "approve"
  approveAction.isDestructive = false
  approveAction.activationMode = .background
  approveAction.isAuthenticationRequired = true
  let denyAction = UIMutableUserNotificationAction()
  denyAction.title = NSLocalizedString("Deny", comment: "Notification deny button title")
  denyAction.identifier = "deny"
  denyAction.isDestructive = true
  denyAction.activationMode = .background
  denyAction.isAuthenticationRequired = true
  let signInCategory = UIMutableUserNotificationCategory()
  signInCategory.setActions([approveAction, denyAction], for: .default)
  signInCategory.identifier = "pushotp"
  let categories = NSSet(object: signInCategory) as? Set<UIUserNotificationCategory>
  let settings = UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: categories)
  DispatchQueue.main.async(execute: {
  UIApplication.shared.registerUserNotificationSettings(settings)
  })
  }

Scenarios

1. When iPhone app is in background and iPhone is locked and watch is in background. If I push a push notification from server , watch displays notification banner with two actions, if I tap any one action , its working fine.
2. when iPhone app is killed and iPhone locked immmediatly If I send pushnotification , watch displays notification banner with two actions, if I tap any one actions its working fine.
3. When iPhone app is killed and iPhone locked, kept both watch and iPhone idle for a hour so. then I will activate the watch and push the notification from server, now watch displays banner with two actions, now if I tap on the actions it is not working.

It would be great if you guys tell me what is the correct thing I have to do.
