Leaflet.RotatedMarker | Leaflet plugin to enable the rotation of map marker icons | Map library

While looking for a way to rotate markers in leaflet.js, I found the module leaflet-rotatedmarker. I installed it via npm, but now I don't know how to actually use it.

As per the readme, it only extends the existing Marker class. To my understanding, I should be able to just call Marker.setRotationAngle() now, but that function does not exist. Importing Marker from leaflet-rotatedmarker does not work either.

How do I properly import the extended class or how do I extend the existing leaflet class with the functions/attributes in the module? Thanks.

I am talking about the import { XYZ } from 'leaflet-rotatedmarker' statement.

Edit:

It also does not work if I try to set the rotationAngle in the constructor:

I have an HTML input tag of type range which I want to use to set the value for rotationAngle of leaflet marker. Also, the rotationAngle must get updated as the user changes the value of .

Also I am using https://github.com/bbecquet/Leaflet.RotatedMarker but cannot set the value using user input.

I want that as input tag value changes the rotationAngle goes on changes.

I am using Leaflet Library (http://leafletjs.com) in a TypeScript project.

I am displaying marker on the map that are configured using options: http://leafletjs.com/reference-1.3.0.html#marker-l-marker

I am trying to use this library in my project: https://github.com/bbecquet/Leaflet.RotatedMarker

I am trying to add more options to second argument of Marker but I am getting typescript errors:
