Hi Omar!
I used your code in my own testbed project, published it, and it did work just fine. I then opened your read-only link and added the code to a new HTML Embed, and it worked fine in the designer (obviously I can not test the published version though).
Can you try re-adding the element and publishing the site to a webflow.io domain so I can take a look at a published version and see what’s different? Let me know where you place it so I know where to look if it still doesn’t load.
Thanks!
