Thank you for the provided information about the license usage.
Also, are you saying, that if I create an automation to send object and embed tags into a rich text field via the object model, sharepoint will strip them?
SharePoint will strip the object and embed tags in SharePoint forms (Lists, Wikis, Blogs, etc.)
scenario and you will experience this problem in the out-of-the box SharePoint rich text editor too.
All the best,
