Spring Boot microservice not reading from rabbitMQ

I have a rabbitMQ container running from docker compose:

services:
  rabbitmq-demo:
    image: rabbitmq:3.13-management # Using management tag for easier monitoring
    hostname: rabbitmq
    ports:
      - "5672:5672" # AMQP port
      - "15672:15672" # Management UI
      - "61613:61613" # STOMP port
      - "15674:15674" # Web STOMP port (for browser-based clients if needed)
    environment:
      RABBITMQ_DEFAULT_USER: guest
      RABBITMQ_DEFAULT_PASS: guest
    volumes:
      - ./rabbitmq-enabled-plugins:/etc/rabbitmq/enabled_plugins:ro # i.e. rabbitmq_stomp

I have a producer spring boot simple microservice which produces STOMP messages

@Service
@EnableScheduling
public class MessageSender implements ApplicationListener<BrokerAvailabilityEvent> { // Implement ApplicationListener

    private final SimpMessagingTemplate messagingTemplate;

...

    @Scheduled(fixedRate = 5000)
    public void sendMessage() {
        if (brokerAvailable) { // Only send if the broker is confirmed active
            String message = "Hello from Producer Service! Message #" + messageCount++;
            System.out.println("Sending message: " + message);
            messagingTemplate.convertAndSend("/topic/public.messages", message);
        } else {
            System.out.println("Broker not active. Skipping message sending.");
        }
    }

That works fine and I see message rate in (0.20/s) in the rabbitMQ ui for amq.topic exchange. I see also messages creation log lines in the app console.

Next I have a consumer spring boot microservice with controller:

@RestController
public class MessageController {

    @MessageMapping("/topic/public.messages") // This maps to the topic Service A is sending to
    public void receiveMessage(@Payload String message) {
        System.out.println("Received message from Producer Service: " + message);
        // You can add logic here to process the received message
    }

    @PostConstruct
    public void init() {
        System.out.println("MessageController @PostConstruct called!");
    }
}

But this is not reading the messages. In the rabbitMQ web ui I see 4 connections (2 stomp, 2 amqp), 4 channels (1 is running with message rate in non-zero). I see the rate on amq.topic exchange, but this topis is not bound to any queue and no queue is created.

Both microservices have common configuration:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(@NonNull MessageBrokerRegistry registry) {
        registry.enableStompBrokerRelay("/topic", "/queue")
                .setRelayHost("localhost")
                .setRelayPort(61613)
                .setClientLogin("guest")
                .setClientPasscode("guest")
                .setSystemLogin("guest")
                .setSystemPasscode("guest");
        registry.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(@NonNull StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").setAllowedOrigins("*").withSockJS();
    }

}

How to fix the consumer to read the messages?
