body: <p>Was just trying to build a simple slack bot by following a YouTube link and started getting the error 
  <strong>Error: not_allowed_token_type</strong> </p>
  
  <pre><code>const bot = new SlackBot({
  token: 'xoxb-TOKEN_GENERATED FROM SLACK SITE',
  name: 'escalatorbot'  // what name should I give here
  })
