Kafka headers are not converted in batch-mode with Spring Cloud 3.0

Question

My question is coming from this discussion: https://stackoverflow.com/a/74306116/3551820

I've added the proper configurations to enable batching consumption but Spring still doesn't work with batch converter to convert the headers of each message (kafka_batchConvertedHeaders).

  @StreamListener(
    target = "command-my-setup-input-channel"
  )
  public void handleMySetup(Message<List<MySetupDTO>> messages) {
    //here Headers are arriving as bytes[]
    List<?> batchHeaders = messages.getHeaders().get(KafkaHeaders.BATCH_CONVERTED_HEADERS, List.class);
    log.warn("Messages received: {}", messages.getPayload().size()); //size of 2

The bean responsible to convert:

@Bean("batchConverter")
BatchMessageConverter batchConverter(KafkaHeaderMapper kafkaHeaderMapperCustom) {
    BatchMessagingMessageConverter batchConv = new BatchMessagingMessageConverter();
    batchConv.setHeaderMapper(kafkaHeaderMapperCustom);
    return batchConv;
}

The configurations below:

spring.cloud.stream:
  kafka:
    binder:
      autoCreateTopics: true
      autoAddPartitions: true
      healthTimeout: 10
      requiredAcks: 1
      minPartitionCount: 1
      replicationFactor: 1
      headerMapperBeanName: customHeaderMapper
    bindings:
      command-my-setup-input-channel:
        consumer:
          autoCommitOffset: false
          batch-mode: true # enabling batch-mode
          startOffset: earliest
          resetOffsets: true
          converter-bean-name: batchConverter # bean mapping
          ackMode: manual
          configuration:

            max.poll.interval.ms: 890000
            value.deserializer: com.xpto.MySetupDTODeserializer
  bindings:
    command-my-setup-input-channel:
      destination: command.my.setup
      content-type: application/json
      binder: kafka
      configuration:
        value:
          deserializer: com.xpto.MySetupDTODeserializer
      consumer:
        batch-mode: true
        startOffset: earliest
        resetOffsets: true

Error:

Bean named 'batchConverter' is expected to be of type 'org.springframework.kafka.support.converter.MessagingMessageConverter' but was actually of type 'org.springframework.kafka.support.converter.BatchMessagingMessageConverter'
