Does anyone know of a way to send an email from the iOS source set in KMM? I've built out the

MFMailComposeViewController

but am unsure how to present it to the user. I've been experimenting and tried:

val rootViewController = UIApplication.sharedApplication().delegate?.window?.rootViewController()
rootViewController?.presentViewController(mfMailComposeViewController, animated = true, null)

But it fails when grabbing the window. I'm not super familiar with iOS concepts so I'm sure there is some fundamental knowledge missing here.
