Disable iframe, url-pasting, embedding in Whiteboard

[teacher1900_2]

I would like to know how I can disable iframe, url pasting and 3rd party integrations/embedding in Zoom whiteboard. This zoom app will used by young children, the relevance of question. The students can access an otherwise blacklisted website like youtube by pasting a url on the whiteboard.

Although, iframes/Pexel has been turned off from Zoom's Advanced Setting page, these options are clearly available on the (Windows) App/software. The web version of zoom seemed to have responded by making those buttons non responsive.

Any help is much appreciated
