How to add deep linking for the notification?

[@ProgrammerWorld]

It depends on the server from which the notification is sent. However, embedding URLs in the text part of the message can be used to send links over notifications.

the app is running but no notofication

[@ProgrammerWorld]

This is a bit tricky App. Build successful means that the App has successfully compiled and installed on your phone, device or emulator.
However, to have it working, it is important that the App is able to listen to the server and has the connection established.
As a quick start, I will suggest to ensure and check whether the json file is correctly placed. If not then please re-download the file and check again.
Also, all the dependencies should be correctly implemented (including their correct versions) in the gradle file, for example:
implementation platform('com.google.firebase:firebase-bom:26.2.0')
implementation 'com.google.firebase:firebase-analytics'
implementation 'com.google.firebase:firebase-messaging:21.0.0'
I do not think there is any other quick approach to diagnose this issue.

How to recieve notification when the app is killed.

[@ProgrammerWorld]

When the App is killed or is not running in your phone then also Push notification will be received because push notification works on OS level and not on individual App. The moment a notification is received by the Android OS it will display it.
Let me know if you are observing any different behaviour.
