server:
  http:
    middlewares:
      current_user:
        session_info:
          session_middleware: session
          information:
            values:
              - preferred_username
              - email
            custom:

Field	Description
session_middleware	Session middleware instance name.
information.values	Claim keys copied into the response.
information.custom	Extra static values added to the response.
information.roles	Include roles parsed from the token.
information.scopes	Include scopes parsed from the token.

The route should usually run after the browser has already logged in, but it does not need to chain session in the same router because it reads the session store by middleware name.
