  # This callback is not global and is per client, thus we do not have to wrap it with a
  # callbacks manager to make it work
  client.delivery_callback = Instrumentation::Callbacks::Delivery.new(
    producer.id,
    producer.transactional?,
    producer.config.monitor
  )

  # Switch to the transactional mode if user provided the transactional id
