Receive a 403 error while using the client credentials flow for machine to machine service (spring boot)

Configuring the server
1

I create a client scope and assign to my client but i can’t handle in my spring boot server
my config security:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true,jsr250Enabled = true)
public class KeycloakSecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.authorizeRequests()
                .anyRequest()
                .permitAll();
        http.csrf().disable();
//        http.authorizeRequests().anyRequest().authenticated();
    }
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
        keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }

    @Bean
    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
    }

    @Bean
    public KeycloakConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }
}

and in controller i use this annotation:

@PreAuthorize("hasAuthority('MyScope')")

But I always get 403
