Hi!
How to remove watermarks from the OSM card?
This is my code:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtLocation 5.12
import QtPositioning 5.12

Item {
    visible: true
    width: 480
    height: 720

    property double old : 19
    property double now

    Rectangle
    {
        anchors.fill: parent
        color: "#eee"

        Plugin
        {
            id: plugin
            name: "osm"
            PluginParameter { name: "osm.useragent"; value: "My great Qt OSM application" }
        }

        Map
        {
            id: maps
            anchors.fill: parent
            plugin: plugin
            gesture.enabled: true
            gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture | MapGestureArea.FlickGesture
            gesture.flickDeceleration: 3000
            zoomLevel: 19
            center: QtPositioning.coordinate(55.845741, 37.660652) // Moscow
            copyrightsVisible: false 
            activeMapType: maps.supportedMapTypes[5] 
            //activeMapType: SatelliteMapNight
            //activeMapType: PedestrianMap
            //activeMapType: MapType.SatelliteMapNight
            //activeMapType: MapType.PedestrianMap


            onCenterChanged:
            {
                if (zoomLevel >= 17.5) 
                {


                }
            }

            minimumZoomLevel: 1

            focus: true

            PlaceSearchModel {
                id: mySearchModel
                plugin: plugin
                searchArea: visibleRegion.boundingGeoRectangle()
                onSearchAreaChanged:  //it's work
                {
                    console.log("onSearchAreaChanged :" )
                    console.log("count :" + mySearchModel.count)
                    if (count == 1) {

                    }

                }
            }

            GeocodeModel {           //Location get(index) должно возвращать координаты
                id: geocodeModel
                plugin: plugin
                onLocationsChanged:
                {
                    //console.log("count: " + geocodeModel.count)
                    //console.log("bounds: " + geocodeModel.bounds)
                    console.log("onLocationsChanged")
                    if (count == 1) {

                        console.log("text:" + geocodeModel.get(0).address.text )
                        console.log("coordinate:" + geocodeModel.get(0).coordinate)
                    }
                }
            }
        }
    }
}
