How do I Pan/Scroll the parent page when dragging/touching on C2 project in an iframe ? (GIF inside)

I can not pan/scroll the whole webpage(Parent page)

when touch and dragging on a C2project

that I've put in an iframe.

.

I want it to work like a normal webpage,

that you can touch and drag

from anywhere on the web

and the whole page will scroll.

.

Here is the problem

this is what I want to achieve.

Thanks
