Can't use on-screen keyboard on tvOS

[dbaldassi]

Hi,

I'm currently porting a C++ Qt(5.12) application on tvOS.
I did a simple navigation implementation to handle the remote's touchpad where I give the focus to widget in function of the X and Y coordinate.

However, when I give the focus to a QLineEdit object and click on the remote, the apple tv on-screen keyboard does not appear, so, I can't enter any text.

Does anyone know if Qt handle the apple tv keyboard and if so, what configuration do I need to do in order to show the keyboard to enter text in a QLineEdit ?
