Add Your External Script:

6- In the Script Manager section, you can add your external script. Depending on where you want to include the script, you can usually choose to add it to the “Header” section.

– Location : All Pages

– Script Category: Essential (Recommended)

Preview and Publish:

It’s a good practice to preview your store to make sure the script works as expected. You can do this by selecting the “Preview” or “View Store” option.
If everything looks good, go back to the theme editor and publish your changes.
Test Your Store:

After publishing the changes, make sure to thoroughly test your online store to ensure that the external script functions correctly and doesn’t interfere with the existing functionality.
