First off, there is no such thing as "wiki owner". You can be the bureaucrat or an admin, but Fandom owns wikis, not the users.

Also, if you want to add an iframe using a Google Sheet, you do not have to set this up as a MediaWiki page, but you can use the extension GoogleDocs4MW. You do not have to install it, and you can use the instructions as mentioned as use there. Fandom uses a slightly different version of that, but code on Github doesn't have any instructions, so it might be easier to follow them on MediaWiki.
