After successfully logging in into a Keycloak realm with openid-connect as protocol, with code as response type, Keycloak will redirect the browser into the redirect uri with param `session_state` and `code` (https://{redirect\_uri}/?session\_state={session\_state}&code={code})

How to let Keycloak server add an additional param to the url? is it needed to extend the server?
