Keycloak session doesn't expire

Question

I have a Spring MVC web app with Spring Security using Keycloak v24.0.2 and Spring Boot v3.2.4. In Keycloak I set up parameters "SSO Session Idle" and "Access Token Lifespan" to 1 minute, but a session still doesn't expire after user being idle during 1 minute. I expect redirection to login screen after being idle this time. What is wrong with my setting? Below is my configuration.

build.gradle

dependencies {
    ...
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'
    ...
}

application.yaml

...
spring:
  security:
    oauth2:
      client:
        registration:
          keycloak:
            client-id: local-client
            client-secret: [my-client-secret]
            scope: openid
        provider:
          keycloak:
            issuer-uri: http://localhost:8180/realms/local-realm
            user-name-attribute: preferred_username
...

MySecurityConfig.java

@Configuration
@EnableWebSecurity
public class MySecurityConfig {
    @Bean
    public SecurityFilterChain configure(HttpSecurity http) throws Exception {
        http.authorizeHttpRequests(auth -> auth
                .anyRequest()
                .fullyAuthenticated())
            .oauth2Login(Customizer.withDefaults())
            .logout(logout -> logout
                .logoutSuccessHandler(oidcLogoutSuccessHandler())
                .permitAll());
        return http.build();
    }
    OidcClientInitiatedLogoutSuccessHandler oidcLogoutSuccessHandler() {
        OidcClientInitiatedLogoutSuccessHandler successHandler =
            new OidcClientInitiatedLogoutSuccessHandler(clientRegistrationRepository);
        successHandler.setPostLogoutRedirectUri("{baseUrl}");
        return successHandler;
    }
}
