How to send device to device push notification in

问题:

I am new to android firebase and notifications. I have created my basic android application in which user(s) of type say x sends a request to user of type y. The request gets generated fine and user of type y can click on the pending request button to see the list of request from user x but i want to inform the user type y through push notification when x generates a request.

Any tutorial or detailed explanation with code would be really helpful as I could not find anything useful til now
