Customize keycloak realm login idle session timeout

The events indicates that the keycloak management console login uses ‘security-admin-console’ client for login. But setting “Client Session Idle”, “Client Session Max” and “Access Token Lifespan” under the client is having no impact on the keycloak session. It seems to be considering the values from “Realm settings”. Is it possible to customize it under the client, or is it always taking the global SSO session values?
