Maps.kt analogously reads:

fun svgOverlay(svgElement: Element, bounds: LatLngBounds, options: ImageOverlayOptions? = null) {
        val overlay = KVManagerMaps.leaflet.svgOverlay(svgElement, bounds.toArray(), options?.toJs())
        if (jsMaps != null) {
            overlay.addTo(jsMaps)
        }
        mapObjects.add(overlay)
    }
