title: Receiving service messages in a group chat using Telegram Bot
body: <p>I am trying to create a bot in my group to help me track the group users who have invited other users into the group.</p>
  
  <p>I have disabled the privacy mode so the bot can receive all messages in a group chat. However, it seems to be that <code>update.message</code> only gets messages supplied by other users but not service messages like <code>Alice has added Bob into the group</code></p>
  
  <p>Is there any way that I can get these service messages as well?</p>
  
  <p>Thanks for helping!</p>
