Zoomlevel in qml map using osm plugin - qt

Question

I have a qml map that uses osm plugin and it is in offline mode. I noticed that the maximum zoomlevel is 19 and I want to increase it. How can I change the maximum zoomlevel using this plugin?
Is there a solution?

onZoomLevelChanged: {
console.log(map.zoomLevel)
}
Component.onCompleted: {
for( var i_type in supportedMapTypes ) {
if( supportedMapTypes[i_type].name.localeCompare( "Custom URL Map" ) === 0 ) {
activeMapType = supportedMapTypes[i_type]
}
}
}
}
}
