Customizing Qt QML Map using Google maps plugins

Question

I am trying to customize QML Map using Google Maps. I am using this plugin by vladest, which adds Google Map support for QtPositioning Map and works as expected, but I didn't find out how to customize it.

I have tried to parametrize Plugin in QML using PluginParameter:

Plugin {
    id: mapPlugin
    name: "googlemaps"

    // specify plugin parameters if necessary
    //PluginParameter {
    //    name:"googlemaps.maps.apikey"
    //    value:"<--------->"
    //}
    //PluginParameter {
    //    name:"googlemaps.maps.identifier" // I have also tried mapId & map_id instead of identifier
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.maps.identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.maps.Map.identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.maps.map.identifier"
    //    value: "8e0a97af9386fef"
    //}
    //PluginParameter {
    //    name:"googlemaps.maps.map.identifier"
    //    value: "8e0a97af9386fef"
}

Map {
    anchors.fill: parent
    plugin: mapPlugin
}

I also studied Google API via styling and I have also tried example of styling via mapId, but didn't manage to make it work.

I have also tried to edit plugin code and add map ID into tile request query, but without success.

Is there any way to customize map?
