Am I adding my google analytics tracking code correctly?

Hello, I’m looking to add my google analytics tracking code in Enfold Child -> Google Services -> Google Analytics Tracking Code. The help text says I can add the full tracking code, so this is what I’ve added:

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXX-X"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-XXXXXX-X');
</script>

Just wanted to double check that this is the correct code to add. Thanks
