        anchors.fill: parent

        plugin: Plugin {
            name: "mapboxgl"
            PluginParameter {
                name: "mapboxgl.access_token"
                value: "pk.eyJ1IjoibWlsYWRsb3ZlYm90aCIsImEiOiJjanZiaHlrZXEwczF5NDRxZnp0cnFseG9jIn0.CZjNPyoSnkUG4NaEzvb36A"
            }
            PluginParameter{
                name: "mapboxgl.mapping.additional_style_urls"
                value: "mapbox://styles/miladloveboth/ckkpdclqt0siu17nppaymn68a"
            }
            PluginParameter {

                value: true
            }

                name: "mapboxgl.mapping.items.insert_before"
                value: "aerialway"
            }
        }

        center: QtPositioning.coordinate(44.190448, 35.402046) // Helsinki
        zoomLevel: 16
        minimumZoomLevel: 0
        maximumZoomLevel: 20
        gesture.enabled: true
        tilt: 45
        activeMapType: map.supportedMapTypes[0]
         MapParameter {
            type: "paint"
            property var layer: "sky"
            property var skyType: "atmosphere"
        }

and i added sky layer at Mapbox Studio, and i can see the Sky layer at my custom mapbox style JSON (search with ctrl+F for "sky" and You can see it) custom mapbox style link so whats my problem? i tried this ways also and i got nothing too:

MapParameter {
                type: "sky"
                property var layer: "sky"
                property var skyType: "atmosphere"
            }

and this:

MapParameter {
                type: "layer"
                property var layer: "sky"
                property var paint:{
                "sky-type": "atmosphere"
                }
            }

and i got some error :

Invalid value for property 'type': 'sky'
