Qt Location: Marking multi addresses on Map

[a-r-t]

Thank you for looking here !

The one question is: How can I use the same plugin connection on both qml & cpp files?

qml file > Plugin{ id: mapPlugin name: "osm" }
and ...
cpp file > QgeoServiceProvider, QGeoCodingManager

(one direction and other direction qml->cpp and cpp->qml plugin)

Main question: I draw multi points on map using the bellow code.
My question is how can I transform the addMarker() function instead of giving Latitude/Longitude to give the address city/street/zip etc names ?

MapView.qml

Item
{
    id: window

    Plugin
    {
        id: mapPlugin
        name: "osm"
    }

    function addMarker(name, lat, lon)
    {
        var component = Qt.createComponent("qrc:///qml/marker.qml")
        var item = component.createObject(window, {coordinate: QtPositioning.coordinate(lat, lon), labelText: name})
        map.addMapItem(item)
    }

    Map
    {
        id: map
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(38, 23)
        zoomLevel: 8

        Component.onCompleted:
        {
            addMarker("house", 38.0, 23.0)
            addMarker("lake", 38.2, 23.2)
            addMarker("church", 38.3, 23.3)
        }
    }
}

marker.qml

MapQuickItem
{
    id: marker
    anchorPoint.x: marker.width / 2
    anchorPoint.y: marker.height / 2
    property string labelText

    sourceItem: Item
    {
        Image
        {
            id: icon
            source: "///images/point.png"
        }

        Rectangle
        {
            id: tag
            anchors.centerIn: label
            width: label.width + 4
            height: label.height + 2
            color: "black"
        }

        Label
        {
            id:label
            text: labelText
        }
    }
}

to be something like ...

    function addMarker(Street, City, Country, State, PostalCode)
    {
         Address {
                   id :markAddress
                   street: Street
                   city: City
                   country: Country
                   state : State
                   postalCode: PostalCode
        }
        
        ...
        map.addMapItem(itemAddress)
    }

or this one ...

    GeocodeModel 
    {
          id: geocodeModel
          plugin: mapPlugin
          autoUpdate: false
    }

    function addMarker(onelineaddress)  //"53 Praxitelis St, Plains, Greece"
    {
          geocodeModel.query = onelineaddress
          geocodeModel.update()
          ...
          ...
          map.addMapItem(itemAddress)
    }
