Google Analytics Embed API..... HELP!

Have been trying to follow a tutorial to connect my site to the GA embed API but the tutorial is formatted to utilize a HTML file uploaded to the site. Since that isn’t in option in webflow, Is it possible to reformat the HTML file provided via the walkthrough in an embed on webflow?

Any Tips, any advice… anything would be greatly appreciated
