When I finish a product demo in-app after signing up, I want to close the demo, so I can get to the value quickly

Love your tool - the best one of it's kind by far!

In the job story above I am describing our use case. We show the user a product demo in-app after they finish onboarding while they are waiting for their marking/grading to complete (what a great experience!). But at the end of the demo they need to click the X (which is small) to get to their marked/graded paper, but it doesn't lend itself nicely to having that final chapter and call to action. If we use a CTA, the page needs to reload which is unnecessary and slower.

The solution might be allowing users to add a CTA action which closes the window.

Thanks!
