Impossible to use qt virtual keyboard in qbs?

```qbs
submodules: [
"keyboard",
"virtualkeyboard",
"qvirtualkeyboard"
]
```
Do not work. How to include qt virtual keyboard module to qbs project?
There is no documentation at all, look here
https://doc.qt.io/qbs/qbsmodules-qmlmodule.html

but qbs has theese modules too:
"concurrent",
"opengl",
"quickcontrols2",
"widgets",
"charts"

I'm just lucky I've found how to use them after some random attempts.
