title: DialogFlow Slack Quick Replies Not working
body: <p>I'm using the <code>Suggestion</code> from <code>dialogflow-fulfillment</code> lib:</p>
  <pre class="lang-js prettyprint-override"><code>const { Suggestion } = require('dialogflow-fulfillment');
  
  ...
  
  agent.add(new Suggestion(&quot;Joke&quot;));
  agent.add(new Suggestion(&quot;Quote&quot;));
  agent.add(new Suggestion(&quot;Movie&quot;));
  agent.add(new Suggestion(&quot;Weather&quot;));
  </code></pre>
  <p>On slack, I get the intended Quick Replies as shown in below image:</p>
  <p><a href="https://i.stack.imgur.com/PYoQe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/PYoQe.png" alt="enter image description here" /></a></p>
  <p>But when I click on these quick reply buttons, these buttons are disabled for 1 sec and are enabled again and this is not firing any request to my DialogFlow agent and thus user have to type these to make it work. How can I solve this?</p>
