  (alternative to `proceedCallback()`)
  
  @param {Object} state - conversation state
  @param {boolean} isText - true if the request is text
  @returns {this}
  @alias module:callbackMiddleware
  @deprecated - use res.runBookmark()
  @example
  bot.use(['fooRoute', /^foo$/], (req, res) => {
  // ability get back to previous context
  res.addCallbackQuickReply('Go back');
  
  res.text('So, what you want?', {
  barRoute: 'Go to bar'
  });
  });
