How to access the ActiveMQ "Classic" statistics plugin in Python

I referred to the ActiveMQ "Classic" documentation to get statistics of broker/queues and create some analysis based on the statistics. I am not able to fetch the stats with following code snippet.

Code snippet::

self.conn = stomp.Connection([('localhost', 61616)] , keepalive=True, try_loopback_connect=True, reconnect_attempts_max=3,)
self.conn.set_listener("testlistener", TestListener(print_to_log=True))
# couple of more listeners for some existing purpose




def retrieve_stats(self) -> None:
  print("*************START*****************n")

  self.conn.subscribe(destination="/queue/test") # created a new queue where stats can be pushed

  self.conn.send(
      body="",
      destination="/queue/ActiveMQ.Statistics.Broker",
      content_type="text/blah",
      headers={
          "amq-msg-type": "text",
          "persistent": "true",
          "reply-to": "/queue/test",
        },
  )
  broker_stat_listener = self.conn.get_listener("testlistener").get_latest_message()
        
  print(broker_stat_listener.__str__())
  print("*************END*****************n")
