How to implement Rest API + Spring Security + oAuth2 + JWT?

Question

Java

Good afternoon.
Please tell me the manual, or the git repository where this bundle is implemented.
I can't figure it out.
The essence of the problem.
We have a mobile application on Flutter.
There is an oAuth2 server with authorization.
You need to write a Backend in Spring so that the mobile application contacts the oAuth2 server, then it sends a request to the Backend, an additional check takes place, and then a JWT is issued for the mobile application, then the mobile application directly addresses our Backend.
I google, and I do not understand how to implement all this. Tell me please.
