Description

I'm getting the following errors when trying to compile a TypeScript project that has auth0 as a dependency:

node_modules/auth0/dist/cjs/lib/models.d.ts:2:28 - error TS2307: Cannot find module 'undici' or its corresponding type declarations.

import { Dispatcher } from 'undici';

### Reproduction

1. Create a TypeScript project using [gts](https://github.com/google/gts).
2. Run `npm install auth0`.
3. Add the following line to the `index.ts` file: `import * as auth0 from 'auth0';`
4. Run `npm run compile` or, alternatively, `tsc`.
