Logout button for kibana with backend saml realm

Our security team recommends to provide a means for user to effectively logout and clear the session. We have configured saml sso login thru saml auth realm plugin in elasticsearch backend. I am looking for a way to enable the logout button on kibana ui

If you have configured SAML correctly the Kibana default logout button should also trigger Single
Logout.

How to disable SLO when my idp does not support it and does not publish anything related to it on its metadata.
But would like a logout button to clear local sessions.
