How to set add my own globals when using jest-preset-angular/global-setup

Question

I would like to be able to set a timezone for all tests to run in globally as outlined in this post. But still setup my jest.config.ts to leverage, either directly or indirectly, jest-preset-angular/global-setup.

It seems there is only one place in the jest.config.ts to set a globalSetup.

This is what I have in my jest-global-setup.js file, which I currently have referenced in my globalSetup but I don't believe this is correct:

module.exports = async () => {
  process.env.TZ = 'UTC';

  return require('jest-preset-angular/global-setup');
};
