On iOS, CTR, ALT, SHIFT and COMMAND keys are not detected

On a iOS app, the CTR, ALT, SHIFT and COMMAND keys are not detected in Qml.

Attached you will find a small application that prints the pressed keys to the console and to the screen. On macOS and Windows all keys of the keyboard print something but the same does not happen on iOS.

In order to create an application that perfoms seamlessly on different operating system I one must have this functionality.

Thank you!
