  <p>Did a simple hears &amp; reply method, working good :</p>
  
  <pre><code>$this-&gt;botman-&gt;hears('foo','HelloWorld@handleFoo');
  $this-&gt;botman-&gt;hears('hello',function($bot){

  <p>But when using <a href="https://botman.io/2.0/conversations" rel="nofollow noreferrer">Botman's conversation method</a>, then Bot is not replying...my conversation code as below:</p>
  
  <pre><code>$this-&gt;load-&gt;library('BotConversations/OnboardingConversation');
  $this-&gt;botman-&gt;hears('sup', function($bot) {
      $bot-&gt;startConversation(OnboardingConversation);
  });
  // Listen
  $this-&gt;botman-&gt;listen();
  </code></pre>
