I'm building an app using Atom Shell, and I'm trying to open an iframe which would load a PDF file, and then, once the PDF file is fully loaded, run some JS from the scope of that iframe (I'm willing to run Browser->Print (https://github.com/atom/atom-shell/blob/master/docs/api/browser-window.md#browserwindowprintoptions)
.
Is that possible? If so, how?
