Routing plugin, hint please

[darionis]

Hello,

I am trying to create a plugin for leaflet-routing-machine.

I started with

@NpmPackage(value = "leaflet-routing-machine", version = "3.2.12")
@JsModule("leaflet-routing-machine/dist/leaflet-routing-machine.js")
@CssImport(value = "leaflet-routing-machine/dist/leaflet-routing-machine.css", themeFor = "leaflet-map")
public class Routing extends Layer {
}

but I am really clueles about JS, so I need a quick hint, how to this with vaadin:

L.Routing.control({
  waypoints: [
    L.latLng(57.74, 11.94),
    L.latLng(57.6792, 11.949)
  ]
}).addTo(map);

I guess I somehow need to get hold of 'control' instance and pass waypoints, right? I will be able to work with it myself, but I just need small hint to get going:

1. how do I get 'control' instance inside my Routing class?
2. is extending Layer ok? Or shoud I extend LeafletControl

I have been through other plugins code, but they seem to be much simpler, so I wasn't able to figure it out myself.

Thanks!
