There is a class with some several methods. One of them:

```
drawGeojson(layerid: string, geojsonObject) {
     this.ngZone.run(() => {}
}

```

How to refactor the code - so that, on request, you can execute the method body with a wrapper

```
 this.ngZone.run(() => {}

```

and without it?

I need something this:

The default call: `drawGeojson()`
The proxy call `Wrapper.drawGeojson();`
