PNG as KML layer on google maps overlapping everything

Question

I'm using KMZ file, that has png file as layer, plus kml file itself with coordinates. However i'm having issue with PNG overlapping an actual map (city names, country names, etc), everything is behind KML layer.

Code:

let kml = new google.maps.KmlLayer('https://***.com/2g.kmz?dummy=' + (new Date()).getTime(), {suppressInfoWindows: true, preserveViewport: false})
this.kml.setMap(this.map)

img[src*="kmz"] {
