Make an Real HTTP Request Using TestCafe

Due to complications with automating certain parts of our workflow strictly through the front-end, we need to make an HTTP request before our front-end automation tests run in order to setup test data.

Using the TestCafe docs I tried piecing something together, and while the test runs, the http request is not getting executed. Here's the code I have:

import {Selector, ClientFunction, RequestHook} from 'testcafe';


class CreateTestMove extends RequestHook {
    async onRequest (event) {
        event.requestOptions.method = "POST";
        event.requestOptions.url = "https://api.com/move/sample";
        event.requestOptions.body["companyKey"] = "xxxxxxxxx";
        event.requestOptions.headers["X-Company-Secret"] = "xxxxxxxxx";
        event.requestOptions.headers["X-Permanent-Access-Token"] = "xxxxxxxx"
    }
}

const customHook = new CreateTestMove();

fixture `Call Create Test Move`
    .before(async ctx => {
      customHook;  
    })

I'm not super familiar with JS, so probably did something obviously wrong here, just not sure what it is.
