title: smooch - "continuing conversation" notifications
body: <p>I recently set up smooch on slack but am only receiving notifications when new users start conversations, not when returning customers continue a conversation as outlined <a href="http://blog.smooch.io/live-chat-vs-new-live-chat-what-this-means-for-customer-service/" rel="nofollow">here</a></p>
  
  <p>How do I solve this?</p>
