Can't find notifications in firebase console after push notification in pyfcm

Question

I'm working on a project where I have to push notifications using pyfcm. I created a firebase project and I took the api key and created an FCMNotification like this :

from pyfcm import FCMNotification

push_service = FCMNotification(api_key="my api key")

Then I create a message and sent it to an already subscribed topic

 data = {"notification" : {
    "body" : "Body of Your Notification",
    "title": "Title of Your Notification"
  }
  }
r = push_service.notify_topic_subscribers(topic_name="user-17", data_message=data)

On this side everything works fine I get the following success message

{'multicast_ids': [], 'success': 1, 'failure': 0, 'canonical_ids': 0, 'results': [], 'topic_message_id': 8479629199217820144}

but in firebase console at https://console.firebase.google.com/u/0/project/project_name/notification it doesn't show the notifications sent by fcm. Although the notifications pushed from postman are being shown.

Please if you can guide me through this I'd appreciate it thanks.
