title: Microsoft BotFramework: How to send raw JSON message to channels?
body: <p>I'm using Node.js and BotBuilder v3.1.1.</p>
  
  <p>Previously, we had <code>Session.sendMessage();</code> that we could use to send raw data to the channel we are connected with.</p>
  
  <p>That proved useful for quick testing and using new features that aren't implemented on the library yet.</p>
  
  <p>How can I do this on the current version v3, since the sendMessage method was removed?</p>
