docs: Adds the same notification action for all the notification statuses.
  So for example, if you want to have the same action while the notification is in progress,
  cancelled, completed or with an error, this method will save you lines of code.
  
  @param action {@link UploadNotificationAction} action to add
  @return {@link UploadNotificationConfig}
