Excel Embedded Content Documentation

Is there a video that shows how to use "Embedded content" feature to manage tags in an Excel file that needs to be translated? I am trying the Trados 2021 version and it is not handling any tags that are inside the Excel file that I need to translate. I am wondering if I am doing something wrong, but there are no clear instructions on how to use this feature that I could find anywhere. If you could let me know, I appreciate it. Thanks. - Tom
