QML accessability issue.

[mutzev]

I'm trying to change the accessibility message without changing the focus.

TextEdit {
    id: searchText
    text: "yellow"
    anchors.centerIn: parent
    focus: true
    Accessible.role: Accessible.StaticText;
    Accessible.name: searchText.text;
    Keys.onPressed: (event) => {
                        if (event.key === Qt.Key_Down){
                            Accessible.description = "red";
                            console.log("down clicked");
                        }
                        if (event.key === Qt.Key_Up){
                            Accessible.description = "blue";
                            console.log("up clicked");
                        }

                    }
}

in QT Widget this works.

    auto *ev =  new QAccessibleValueChangeEvent(focusedWidget, "New Message");
    QAccessible::updateAccessibility(ev);

I am looking for a QML solution
