Why is the function not being called?

Question

Node.js

https://www.npmjs.com/package/wdio-intercept-service

I write the code as in the example (Usage with WebDriver Standalone section):

import WebdriverAjax from 'wdio-intercept-service';
const interceptServiceLauncher = WebdriverAjax();

And I get an error from TS. Is the documentation not up to date or am I doing something wrong?

Cannot use namespace 'WebdriverAjax' as a value.ts(2708)

How to fix it?
