Keycloak saml logout in cognito

I am using Keycloak saml Identity provider in AWS Cognito to log in. What configuration I need to do in keycloak Saml Client to perform a logout So that User Can logout from the Cognito and session is deleted from keycloak as well and should redirect back to keycloak login page?
If a User session is logged out from Keycloak admin console then the User should also redirected back to the login page.
