How to draw routes on the map?

L.Gogs

Hello everyone!!
I want to display Map and draw lines on it.

I have qml code but routes aren't displayed.
Does anybody know how to draw?

My code:
```

Item
{
    Map
    {
    id: map
    anchors.fill: parent
    plugin: Plugin{name: "MBTiles"}
    center: QtPositioning.coordinate(42.25277166666667, 42.68047166666667)
    zoomLevel: 30

    MapQuickItem
    {
        coordinate: QtPositioning.coordinate(42.25277166666667, 42.68047166666667)
        sourceItem: Image
        {
            id: image
            source: "qrc:/new/m.png"
        }
    }
    MapItemView
    {
        model: routeModel
        delegate: Component
        {
            MapRoute
            {
                route: route
                line.color: "blue"
                line.width: 5
            }
        }
    }
}

RouteModel
{
    id: routeModel
    plugin: map.plugin
    query: RouteQuery {id: routeQuery}
    Component.onCompleted:
    {
        routeQuery.addWaypoint(QtPositioning.coordinate(42.25277166666667, 42.70047166666667))
        routeQuery.addWaypoint(QtPositioning.coordinate(42.25277166666667, 42.68047166666667))
        update();
    }
}

}
