I have only kafka consumer in my code, below is the configuration:

@Configuration
@RequiredArgsConstructor
public class OrderGraphKafkaConsumerConfig {
    public static final String SECURITY_PROTOCOL_CONFIG = "SASL_SSL";
    public static final String PLAIN = "PLAIN";
    public static final String CONNECTION_STRING = "$ConnectionString";
    public static final String SASL_JASS_CONFIG = "%s required username="%s"  password="%s";";

    private final OrderGraphConfiguration configuration;


    @Bean
    public ConsumerFactory<Object, Object> consumerFactory() {
        Map<String, Object> props = new HashMap<>();
        props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, configuration.getBootstrapServers());
        props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        props.put(ConsumerConfig.GROUP_ID_CONFIG, configuration.getGroup_id());
        props.put(ErrorHandlingDeserializer.KEY_DESERIALIZER_CLASS, StringDeserializer.class);
        props.put(ErrorHandlingDeserializer.VALUE_DESERIALIZER_CLASS, StringDeserializer.class);
        props.put(JsonDeserializer.USE_TYPE_INFO_HEADERS, false);
        props.put(JsonDeserializer.TRUSTED_PACKAGES, "*");

        props.put(CommonClientConfigs.SECURITY_PROTOCOL_CONFIG, SECURITY_PROTOCOL_CONFIG);
        props.put(SaslConfigs.SASL_MECHANISM, PLAIN);
        props.put(SaslConfigs.SASL_JAAS_CONFIG, SASL_JASS_CONFIG.formatted(
                PlainLoginModule.class.getName(),
                CONNECTION_STRING,
                configuration.getSaslJassPsw()
        ));

        return new DefaultKafkaConsumerFactory<>(props);
    }
}

And here is application.yaml (with my tries so far)

  kafka:
    bootstrap-servers: localhost:7042
    consumer:
      auto-offset-reset: earliest
      security:
        protocol: SASL_PLAINTEXT
    properties:
      message.max.bytes: 524288000
    security:
      protocol: SASL_PLAINTEXT


kafka-clients-configuration:
  my_component:
    topics: test_topic
    bootstrapServers: localhost:7042
    group_id: group-test
    sasl_jass_psw: psw

I tried to play with the application yaml as I saw in many answers buy nothing works for me…
How can I send a kafka message in test, without create a producer?

Additonal Info:
spring-boot: 3.3.1
spring-kafka: 3.2.1
kafka-clients: 3.7.1
spring-kafka-test: 3.2.2
