This article talks about embedding content like Youtube videos, music and maps onto your site using an embeddable code.
Add embeddable content block
Click Add UI Block in the editor and select content. You should see a block for embedding content.

Editing the block
Hover over the content block and click on Edit. A panel should appear on the right with options to edit the embed code. We only want the src URL part.

For example, most embed code will come in the form of an iframe.
<iframe width="560" height="315" src="https://www.youtube.com/embed/4BUZwti7F5Y" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
Copy the url inside i.e. https://www.youtube.com/embed/4BUZwti7F5Y
