We embed Supademo links inside our application using an iframe. Our goal is to automatically close a modal once a user completes the demo — specifically after they reach the final slide and a short delay has passed.

Right now, we don’t see any way to detect when a demo has finished playing. It would be extremely helpful if Supademo could provide:

• A completion event listener or callback API

• A postMessage trigger to the parent window when the final slide is viewed

• Any mechanism to notify the host app of completion status

This would allow seamless integration and improved UX for embedded demos within products.

Would love documentation or implementation guidance if something like this already exists.

Thanks!
