title: Sending WhatsApp interactive message of list type fails when sent with image header
body: <p>I am able to send interactive message with &quot;button&quot; type and 3 buttons with image header.
  But sending interactive message with &quot;list&quot; type and same image header fails with error:</p>
  <pre class="lang-json prettyprint-override"><code>{
    &quot;meta&quot;: {
      &quot;api_status&quot;: &quot;stable&quot;,
      &quot;version&quot;: &quot;2.39.4&quot;
    },
    &quot;errors&quot;: [
      {
        &quot;code&quot;: 1008,
        &quot;title&quot;: &quot;Required parameter is missing&quot;,
        &quot;details&quot;: &quot;Failed building interactive message. Invalid Header.&quot;
      }
    ]
  }
  </code></pre>
  <p>Is it possible that &quot;list&quot; interactive messages doesn't support &quot;image&quot; header without stating it in documentation?</p>
