title: Display unread messages per subcribed Yammer group
body: <p>In the Yammer app on mobile as well as in the desktop version a count of the unread messages is shown for each group. I cannot find how to retreive this information from the API.</p>
  
  <p>How can I show the number of unread messages for each group for every user?</p>
  
  <p>A workaround using <a href="https://www.yammer.com/api/v1/messages/in_group/:group_id.json" rel="nofollow noreferrer">https://www.yammer.com/api/v1/messages/in_group/:group_id.json</a> with newer_than parameter will not suffice as the counts will not be synchronised between the Yammer site and my app.</p>
