Restrict Users To Contact anyone other than embedded Zoom SDK

I am working on a web application(ROR + React). My application will be used in prisons and the prison management whitelists all the urls and will only allow my application url. I am aware that the Zoom meeting SDK will need some urls to work. But the prison management wont allow it as it compromises security and the prisons can create meetings or contact someone outside. Is there any approach or solution to this particular use case?.
