Google Map api metrics (api key) not working with vladest plugin

isstar

Hi. I made simple project in Qt Creator with QML and https://github.com/vladest/googlemaps. The map is working fine, but Google doesn't see my api key activity. I have another project on JS with the same api key, which activity is being recognized by Google. I enabled all api's in my google maps account.

Rectangle
{
width: 1024
height: 600

    Plugin
    {
        id: mapPlugin
        name: "googlemaps"
        PluginParameter
        {
            name: "googlemaps.apikey"  //no metrics
            //name: "googlemaps.maps.apikey"   //no metrics
            value: "AI........................................mE"
        }
    }

    Map
    {
        id: map
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(59.919716, 30.277555)
        zoomLevel: map_zoom_level

I rebuild plugin, adding direct specifing of api key like this:

if (parameters.contains(QStringLiteral("googlemaps.places.apikey")))
    m_apiKey = parameters.value(QStringLiteral("googlemaps.places.apikey")).toString().toLatin1();
else
    m_apiKey = parameters.value(QStringLiteral("googlemaps.apikey")).toString().toLatin1();

m_apiKey = "AI................................................mE";

I found 4 .cpp files where i can do it. I redeployed project, and refreshed plugin library files in the project and Qt folders. No metrics.

Qt_5_15_2_MinGW_64_bit-Release
Windows 10 - no metrics
Debian Bullseye - no metrics

By the way, should I see any metrics with this plugin? The map is working even without api key specification.
