title: How to join a Slack channel as a Real Time Messaging bot user?
body: <p><code>channels.join</code> is <a href="https://api.slack.com/methods/channels.join" rel="noreferrer">not allowed</a> for bot users.  I would like my RTM-using bot to listen to channels other than the one listed in the bot integration page.</p>
  
  <p>I don't see a way to change the channels in the bot integration page:</p>

  <p>Is this just a limitation of bots or am I missing something fundamental here?</p>
