How do I make a scrollable image inside a mobile screen?

I want to have a mobile mock-up on the website, like this one: https://mockup-scroll.webflow.io/

But when I apply the image, it doesn’t scroll inside the mock-up. What am I doing wrong?

Thanks!

Can you share a read-only link?

It’s bringing me to a 404. Did you take it down?
