  NSLog(@“Push Plugin handleActionWithIdentifier %@”, identifier);
  NSMutableDictionary *userInfo = [notification mutableCopy];
  [userInfo setObject:identifier forKey:@“actionCallback”];
  NSLog(@“Push Plugin userInfo %@”, userInfo);

  pushHandler.notificationMessage = userInfo;

  } else {

  completionHandler();
  });
  };

    PushPlugin *pushHandler = [self getCommandInstance:@"PushNotification"];
