Unable to receive push notification in standalone app

Hi

As per the following link I am able to receive the fcm token in standalone app. But when I am sending push notification, the app is not receiving it. The interesting thing is, in the same app I am receiving the push notification from expo using expo token. Please help me out.

https://docs.expo.io/versions/latest/sdk/notifications.html#exponotificationsgetdevicepushtokenasyncconfig

the expo sdk version I am using is 23.0.0

Thanks

Notifications sent through FCM need to be in a very specific format that may change in a future SDK release. The format is not part of the public API, so if you send notifications directly you may need to debug the code yourself if you encounter issues. Here are a couple of places to start:

Once again, these are all internal details and may change in any SDK release so please set expectations that this might not be stable.
