IONIC 5 FCM Plugin onNotification not fired when app is killed/closed (IOS & Android)

cordova

I am stuck with a problem in both platforms with FCM plugin (https://ionicframework.com/docs/native/fcm), the problem is I can´t handle notifications when app is closed/killed , the onNotification() method isn´t fired (it works fine in background and foreground)

this.fcm.onNotification().subscribe((payload) => {
          if (payload.wasTapped) {
            console.log('Notification received in background');
          } else {
            console.log('Notification received in foreground');
          }
          console.log('Notification payload: ',payload);
  });

notification body working fine in background and foreground (both platforms):

{
 "to" : <device-key>,
"collapse_key" : "app-key",
 "notification" : {
     "body" : "body",
     "title": "title"
 },
 "data" : {"parameter":"1"},
 "android": {
    "notification": {
      "click_action": "FCM_PLUGIN_ACTIVITY"
    }
  }
}

The ionic info output for IOS environment:

it will work if you send the things from postman. If you send the notification from firebase console it will not work. you can refer this click here thread.
