Here's how it all looks when you put it together:
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1, shrink-to-fit=no"
    />
    <script
      type="text/javascript"
      src="https://cdn.intelligence.weforum.org/latest.js"
    ></script>
    <style>
      intelligence-widget {
        --textColor: darkGrey;
        --thumbnailRadius: 5px;
        --fontFamily: Biotif, sans-serif;
      }
    </style>
  </head>

  <body>
    <intelligence-widget
      apikey="my-api-key"
      topicid="my-topic-id"
      language="en"
    >
    </intelligence-widget>
  </body>
</html>
