instantiate a new drawing with a custom control

[cscrum]

I'm attempting to create a custom control to draw a polygon. I can successfully add the toolbar and draw a polygon using the buttons, but I want to do this through a custom toolbar. I'm trying this:

this.polygonDrawer = new Draw.Polygon(this.map,{
metric: false,
feet: false,
shapeOptions: {
color: '#85bb65',
},
})

however it doesn't like the this.map argument. this.map is the instance of my leaflet map in the Angular project. I get an error:
Argument of type 'Map' is not assignable to parameter of type 'DrawMap'.
Type 'Map' is missing the following properties from type 'DrawMap': mergeOptions, addInitHook

DrawMap seems to be a specific type that I can't find a reference for, but TS tells me it is this:
DrawMap(element: string | HTMLElement, options?: MapOptions): DrawMap
I'm not sure how this is supposed to relate to the leaflet map. Why would I need a different reference to the map other than the map I already have?

import * as L from 'leaflet';

this.currentlyDrawnShape = new L.Draw.Circle(this.mapInstance as L.DrawMap, this.drawOptions.draw.circle); this.currentlyDrawnShape.enable();

This is how I made it and it works...
