Hi want to provide you with a simple and efficient workaround to embed videos, maps, or other resources in the Wagtail Admin. Please follow these steps:

1. Use the paragraph block for text.
   
2. Add an HTML block to paste in the embed code from YouTube or the desired resource.
   
3. For example, on YouTube, click "Share" and choose "Embed," then copy the provided code and paste it into the HTML block on Wagtail.
