Slack Botkit - How to get a message's content from a 'reaction_added' event
<p>I'm using the <strong>botkit</strong> framework to respond when a reaction is added to a message but I'm not sure how to extract the message's content when the event is triggered. Below is what I currently have: </p>

<pre><code>controller.on('reaction_added',function(bot, event) {

   if (event.reaction == 'x') {
      // bot reply with the message's text
   }
});
</code></pre>

<p>According to the <a href="https://api.slack.com/events/reaction_added" rel="noreferrer">Slack API</a>, I can only get data like event.item which has the type, channel, and ts of the message. Does anyone know how to accomplish this?</p>
