How to implement dead letter queue in WebFlux react kafka?

Question

May I know how to implement dead letter queue example for the below code? The same input record should be published to some dlq topic.

reactiveKafkaConsumerTemplate
                .receiveAutoAck()
                .map(ConsumerRecord::value)
                .flatMap(this::consumeWithRetry)
                .onErrorContinue((error, value)->log.error("something bad happened while consuming : {}", error.getMessage()))
                .retryWhen(Retry.backoff(30, Duration.of(10, ChronoUnit.SECONDS)))
                .subscribe();

public Mono<Void> consumeWithRetry(MessageRecord message){
   return consume(message)
          .retry(2);
}

public Mono<Void> consumeWithRetry(MessageRecord message){
   return Mono.defer(()->consume(message))
          .retry(2);
}
