Delivers a local notification payload and a user-selected action to the app.

The action selected by the user. The string is the identifier for an action that was registered by the companion iOS app; it identifies which button was tapped by the user. Use the identifier to perform the associated action. This parameter is set to the empty string when the user launches the app without tapping one of the action buttons.
The local notification object that triggered the notification.
Use this method to handle actions selected by users from your notification interfaces. If your containing iOS app supports interactive notifications, the
identifier parameter may contain the action identifier for the button that was tapped. Use that value to perform the requested action. If the
identifier parameter contains an empty string, that means the user launched your Watch app from the notification interface without choosing a specific action.
The system calls this method on your WatchKit extension’s main thread. The
super implementation of this method does nothing.
