Example of using geometric pattern with Highmaps in React?

Does anyone have an example of creating (geometric) patterns using Highmaps in React?

I'm initialising Highmaps as follows:

this.chart = new HighMaps["Map"](findDOMNode(this), options);

That works fine.

I'm attempting to import the pattern module as follows:

import * as patternFill from "highcharts/modules/pattern-fill";

Not sure if that's correct, because I'm not sure how to then "wire" the module up with Highmaps given the earlier code.

I'm basically trying to use a hatch pattern on certain countries rather than a solid colour. Highmaps is working fine---it's just the pattern stuff that has me stumped.
