title: Twilio Chat getChannels order by most recent message
body: <p>In twilio chat, is there a way to specify an order to the <code>getChannels()</code> method? Or is there a property on the <code>Channel</code> object that will tell me when the last message sent on that channel was? The <code>dateUpdated</code> property on Channel seems to be when properties on the channel were updated, not including messages sent/received.</p>
  
  <p>I would like to order my channels list by the most recent messages. And I would like to do this without having to retrieve all the messages first.</p>
