OAuth Revoke and Logout
We need to test the revoking of issued OAuth tokens (https://docs.spring.io/spring-authorization-server/docs/current/reference/html/protocol-endpoints.html#oauth2-token-revocation-endpoint) and instructions for UI what API call to make.
Please test the current implementation and provide feedback on how UI can properly log out authorized clients.
