RabbitMQ send messages to specific queue for a specific user

I'm trying to set up a STOMP relay using RabbitMQ, Springboot, and ReactJS. I just want to be able to send a specificnotification to a specific userId.

At this stage I'm not trying to secure anything, I'm just trying to get a concept working.

Using a WebSocketChatConfig of:

@Configuration@EnableWebSocketMessageBrokerpublic class WebSocketChatConfig implements WebSocketMessageBrokerConfigurer {    @Override    public void registerStompEndpoints(StompEndpointRegistry registry) {        registry                .addEndpoint("/websocket")                .setAllowedOriginPatterns("*")                .withSockJS();    }    @Override    public void configureMessageBroker(MessageBrokerRegistry registry) {        registry.enableStompBrokerRelay("/queue/user.notification")                .setRelayHost("localhost")                .setRelayPort(61613)                .setClientLogin("guest")                .setClientPasscode("guest")                .setAutoStartup(true);    }}

And a RabbitConfig of:

@Configurationpublic class RabbitConfig {    private static final String TOPIC_EXCHANGE_NAME = "sockets-exchange";    private static final String ROUTING_KEY_NAME = "user.notification.#";    private static final String QUEUE_NAME = "notifications";    @Bean    public Queue queue() {        return new Queue(QUEUE_NAME, true);    }    @Bean    public TopicExchange exchange() {        return new TopicExchange(TOPIC_EXCHANGE_NAME);    }    @Bean    public Binding binding(final Queue queue, final TopicExchange exchange) {        return BindingBuilder.bind(queue).to(exchange).with(ROUTING_KEY_NAME);    }    @Bean    public RabbitTemplate rabbitTemplate(final ConnectionFactory connectionFactory) {        final RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);        rabbitTemplate.setMessageConverter(messageConverter());        return rabbitTemplate;    }    @Bean    public Jackson2JsonMessageConverter messageConverter() {        return new Jackson2JsonMessageConverter();    }}

I can send messages which are going to Rabbit, via a simple test scheduler

@Slf4j@Component@EnableScheduling@RequiredArgsConstructorpublic class TestTask {    private static final String TOPIC_EXCHANGE_NAME = "sockets-exchange";    private static final String ROUTING_KEY_NAME = "user.notification";    private final RabbitTemplate rabbitTemplate;    @Scheduled(fixedRate = 15, timeUnit = TimeUnit.SECONDS)    public void process() {        rabbitTemplate.convertAndSend(                TOPIC_EXCHANGE_NAME, "%s.1".formatted(ROUTING_KEY_NAME), "This is for user 1");        rabbitTemplate.convertAndSend(                TOPIC_EXCHANGE_NAME, "%s.2".formatted(ROUTING_KEY_NAME), "This is for user 2");    }}

But while I can connect to the queue via React, I'm not getting any response back when a message is pushed into thequeue.

function SubscribingComponent() {    const [lastMessage, setLastMessage] = useState("No message received yet");    useSubscription("/queue/user.notification.1", (message) => {        setLastMessage(message.body)    });    return (<div>Last Message: {lastMessage}</div>    );}

When I look in the Rabbit Management UI I can see three queues are created:
