How to integrate Keycloak SSO and SLO with Kafka-UI and AKHQ using OIDC?

[hooriehghahremani]

I am trying to integrate Keycloak with Kafka-UI, using the OIDC (OpenID Connect) protocol for Single Sign-On (SSO) and Single Logout (SLO). I have successfully implemented SSO with the identity provider, but I am facing an issue with SLO.
My expectation is that when I log out from Keycloak, I should be logged out from all clients, and vice versa. However, when I log out from Kafka-UI, I am logged out from Keycloak as expected, but the reverse does not work — logging out from Keycloak does not log me out from Kafka-UI.
Here are the configuration setting for these services:
Kafka-UI config:

auth:
  type: OAUTH2
  oauth2:
    client:
      keycloak:
        clientId: kafka-ui
        clientSecret: ******
        scope: openid
        issuer-uri: https://keycloak/realms/myrealm
        user-name-attribute: preferred_username
        client-name: keycloak
        provider: keycloak
        custom-params:
          type: keycloak
          logoutUrl: https://keycloak/realms/myrealm/protocol/openid-connect/logout

Keycloak setting:

Client ID: kafka-ui 
Enabled: ON
Client Protocol: openid-connect
Standard Flow Enabled: ON
Implicit Flow Enabled: OFF
Direct Access Grants Enabled: ON 
OAuth 2.0 Device Authorization Grant Enabled: ON
Root URL: https://kafka-ui   
Valid Redirect URIs: https://kafka-ui/*   
Web Origins: https://kafka-ui   
Admin URL: https://kafka-ui   
Root URL: https://kafka-ui   
Valid post logout redirect URIs: https://kafka-ui/logout    
Front channel logout Enabled: ON
Front-channel logout URL : https://kafka-ui/logout   
Backchannel logout URL: https://kafka-ui/logout    
Backchannel logout session required Enabled: ON
Backchannel logout revoke offline sessions Enabled: ON / OFF
