Qt Webassembly number of screens

AliGB

How can I find the number of screens/monitors that are available?
Is this possible from Qt Webassembly?

Edit:
I understand there is a way to get the number of screens from Qt as follows:

auto screens = qApp->screens();
for (int i = 0; i < screens.count(); ++i) {
    qDebug() << i + 1 << screens[i]->geometry();
}

However When I use this in Qt Webassembly, it gives the wrong information.
Is there any way to get around the Qt Webassembly not being able to call this system call properly?
