title: Remove Unused Javascript
body: <p>When we run our app that has been built on nextjs and is hosted on Heroku through Lighthouse and we keep getting a warning saying to &quot;Remove unused JavaScript&quot;.</p>
  <p>Two of the javascript files listed to be removed are:</p>
  <ol>
  <li><a href="https://widgetbe.com/widget" rel="nofollow noreferrer">https://widgetbe.com/widget</a></li>
  <li><a href="https://widgetbe.com/agent" rel="nofollow noreferrer">https://widgetbe.com/agent</a></li>
  </ol>
  <p>We don't host this code anywere whithin our app including our dependencies. How can I ensure that 1) these are not malicious files that somehow made it into this project and 2) remove them</p>
