cant figure out exactly how to implement route display in my kmp project

[avivorel]

currently, my code goes like this:
`

    private fun buildStyleWithRoutes(): Style.Builder {
    val builder = Style.Builder().fromUri(mapStyle.uri)

    routes.forEach { route ->
        val sourceId = route.id
        val layerId = layerIdFor(route.id)

        val geoJson = Feature.fromGeometry(
            LineString.fromLngLats(route.points.map { pt ->
                Point.fromLngLat(pt.lon, pt.lat)
            })
        )

        builder.withSource(
            GeoJsonSource(sourceId, geoJson, GeoJsonOptions())
        )

        val colorHex = String.format("#%06X", route.color and 0xFFFFFF)
        builder.withLayer(
            LineLayer(layerId, sourceId).withProperties(
                lineColor(colorHex),
                lineWidth(route.widthPx),
                lineCap(Property.LINE_CAP_ROUND),
                lineJoin(Property.LINE_JOIN_ROUND),
                visibility(if (route.visible) Property.VISIBLE else Property.NONE)
            )
        )
    }

    return builder
}

and then, I use it like this:
mapSnapshotter = MapSnapshotter( applicationContext, MapSnapshotter.Options(imgWidth, imgHeight) .withLogo(false) .withStyleBuilder(styleBuilder) )

for IOS though, I cant seem to implement with the same logic.
heres the style builder:
fun buildStyleWithRoutes() : MLNStyle{ val style = MLNStyle() var polyline : MLNPolyline for (route in routes) { if (!route.visible) continue // Convert route coordinates to CLLocationCoordinate2D array val coordList: List<CValue<CLLocationCoordinate2D>> = route.points.map { point -> memScoped { cValue<CLLocationCoordinate2D> { latitude = point.lat longitude = point.lon } } } memScoped { val coordinatesPointer = allocArray<CLLocationCoordinate2D>(coordList.size) coordList.forEachIndexed { index, coordinate -> coordinatesPointer[index].latitude = coordinate.useContents { latitude } coordinatesPointer[index].longitude = coordinate.useContents { longitude } } polyline = MLNPolyline.polylineWithCoordinates( coordinatesPointer, count = coordList.size.toULong() ) } val sourceId = "route-source-${route.id}" val shapeSource = MLNShapeSource(identifier = sourceId, shape = polyline, options = null) style.addSource(shapeSource) val layerId = "route-layer-${route.id}" val lineLayer = MLNLineStyleLayer(identifier = layerId, source = shapeSource) lineLayer.lineColor = NSExpression.expressionForConstantValue(route.color.toUIColor()) lineLayer.lineWidth = NSExpression.expressionForConstantValue(NSNumber(double = route.widthPx.toDouble())) lineLayer.lineCap = NSExpression.expressionForConstantValue("round") // round line endpoints style.addLayer(lineLayer) } return style }
but I dont know how and where to use it on my ios implementation in my kmp app, cant find it in documentation either.
