How to remove gray screen when launching QT Quick QML App on Android device?

Question

Android

I launch the example application Qt Quick Controls 2 - Gallery on an android device, I
see such a gray window before launching the application:

I tried to add QSplashScreen before launching the app and also separately register it in AndroidManifest.xml

<!-- Splash screen -->
<!-- meta-data android:name="android.app.splash_screen_drawable"android:resource="@drawable/logo"/-->
<!-- meta-data android:name="android.app.splash_screen_sticky" android:value="true"/-->
<!-- Splash screen -->

Splash appears after the gray window and before launching the application itself.
Can anyone tell me how to remove this or should I ask a question on https://forum.qt.io ?
