How can I verify my domain on Facebook without coding experience?

To get my shopify verified on Facebook, I have to do one of these three options:

  1. Add a DNS TXT entry to your DNS record to confirm that you own the domain
  2. Upload an HTML file provided by Facebook to your web directory and confirm domain ownership in Business Manager.
  3. Add a meta tag to the section of your domain home page

Not sure how to address this, I do not have coding experience and honestly do not understand what any of those words mean. Help?
