cornerstoneTools.init() returns undefined

Hello !

I am trying to create an angular application using cornerstone and cornerstoneTools and i am facing an issue when initializing corenerstonetools : the cornerstoneTools.init() function returns undefined.

import Hammer from 'hammerjs'
import * as cornerstone from 'cornerstone-core';
import * as cornerstoneMath from 'cornerstone-math';
import * as cornerstoneTools from 'cornerstone-tools';

class SomeComponent {

constructor() {
    cornerstoneTools.external.Hammer = Hammer;
    cornerstoneTools.external.cornerstone = cornerstone;
    cornerstoneTools.external.cornerstoneMath = cornerstoneMath;
    const csTools = cornerstoneTools.init(this.cornerStoneConfig); //  <-- Undefined : 
    console.log(csTools);

  }
}

Here is a small example showing what i am trying to do : stackblitz example

Any help would be appreciated and thank you.
