title: Add custom javascript to wix
body: <p>I am trying to add custom javascript to wix, but it doesnt work. I have tried almost all I found on google but it doesnt work.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      window.parent.location.href = "https://url/track"
  &lt;/script&gt;
  </code></pre>
  
  <p>The script above needs to be loaded on every wix page, it contains redirection</p>
  
  <p>I was wondering if this is possible in wix?</p>
