In-Browser Recorder

what options available to do an in-browser recording of a webpage not controlled by the user ? Use case is, user will input any webpage URL and there should be a button to record the users browser interaction. The webpage url user entering can be an iframe or some other option (i am open to ideas). Option I explored

01. Writing a chrome extention - Wont work for my use case 02. rrweb - doesnt support iframes interaction capture due to security

thanks
