Does startSystemResize() work on MacOS?

[idkfa]

I'm making a multiplatform app with custom shaped main window and I need to move the native resizing edge 40px from ApplicationWindow edge. So I decided to use custom resizing mechanism. I found this example and tried it in my project but resizing doesn't work on MacOS. It works fine on Windows though. I made a simple project to test startSystemResize() and it always returns "false". Am I missing something or startSystemResize() doesn't work on MacOS?

import QtQuick

Window {
    width: 640
    height: 480

    visible: true
    title: qsTr("Hello World")
    flags: Qt.Window | Qt.FramelessWindowHint

    // DragHandler {
    //     onActiveChanged: if (active)
    //                          startSystemMove()
    // }
    MouseArea {
        id: mouseArea
        anchors.fill: parent
        hoverEnabled: true
        acceptedButtons: Qt.LeftButton

        property int edges: 0
        property int edgeOffest: 5

        function setEdges(x, y) {
            edges = 0
            if (x < edgeOffest)
                edges |= Qt.LeftEdge
            if (x > (width - edgeOffest))
                edges |= Qt.RightEdge
            if (y < edgeOffest)
                edges |= Qt.TopEdge
            if (y > (height - edgeOffest))
                edges |= Qt.BottomEdge
        }

        cursorShape: {
            return !containsMouse ? Qt.ArrowCursor : edges == 3
                                    || edges == 12 ? Qt.SizeFDiagCursor : edges == 5
                                                     || edges == 10 ? Qt.SizeBDiagCursor : edges & 9 ? Qt.SizeVerCursor : edges & 6 ? Qt.SizeHorCursor : Qt.ArrowCursor
        }

        onPositionChanged: setEdges(mouseX, mouseY)
        onPressed: {
            setEdges(mouseX, mouseY)
            if (edges && containsMouse) {
                console.log(startSystemResize(edges))
            }
        }
    }
}
