How to use this plugin in typescript project?

[roddc]

I am trying to use this plugin in my Angular project, I have below type definition for the plugin, but it is not working,
I got an error : L.Handler.MarkerDrag is not a constructor, and I don't find any definition for this class

 declare module "leaflet" {
   namespace Handler {
    export class MarkerSnap extends L.Handler {
     constructor(map: L.Map, marker: L.Marker | L.CircleMarker, options?: any);
     initialize(
     map: L.Map,
     marker: L.Marker | L.CircleMarker,
     options?: any
     ): void;

   watchMarker(marker: L.Marker | L.CircleMarker): void;
   unwatchMarker(marker: L.Marker | L.CircleMarker): void;
   addGuideLayer(layer: L.Layer): void;
   }
   export class MarkerDrag extends L.Handler {
     constructor(marker: L.Marker | L.CircleMarker);
   }
 }
}

L.Handler.MarkerDrag comes from Leaflet.Draw

L.Handler.MarkerDrag comes from Leaflet.Draw

Well, I did find it in the leaflet.draw-src.js file, but I have no idea how to give a definition for it, I have leaflet-draw javascript and typescript installed
