Return to Question

I have a KML file which I need to import in a map using Leflet. If I use leaflet-kml I can see all polygons with color set from KML file. But because I need to show only one polygon extracted for this file, in another question, someone suggest to use leaflet-omnivore which allow me to do that. In this way, for some reason can't read the style in KML and use the blue for all polygons.

        }).addTo(map);

        map.attributionControl.setPrefix('');

            // Load kml file
            fetch('doc.kml')
                .then(res => res.text())
                .then(kmltext => {

                    map.addLayer(track);

                    // Adjust map to show the kml
