Ionic docs demo device?

I would like to use something like the little demo-device found in all the angular docs.

I have a web portal that controls dynamically some of the content of the app and I really would like to have a demo device exactly like in the docs that renders what the content my look like as a preview.

It looks like the docs are using an iframe that runs the ionic demo code. But there’s some cool stuff like simulating the actual Ios or android functionality that I have no idea how it’s being done?

Out of interest did you ever manage to find a solution to this, I would like to do exactly the same in my PWA to preview content to the user.

Thanks

Yes I inspected on the browser and found out their using iframes. So I setup a browser build of the app. and routed to it in the iframe using nginx and it works great
