How use Spring Boot oAuth2 + Azure AD in a stateless micro-service? - spring

Question

When I try the sample code from Microsoft Azure to use oAuth2 and Spring Boot, it uses a stateful session to check authentication/authorization. You can see this in that:
It never passes any headers/JWT on any calls
It has a cookie "JSESSIONID" that you can use in new postman session (after obtaining it in a different browser) and it will consider you logged in
This will not work as our micro-services will be multiple instances.
How could I convert this to use a JWT (Authorization: Bearer AQab...) for subsequent calls instead of the cookie?
