firebase-functions has no exported member 'auth'

This piece of code is watching for the user auth event:

export const onUserAuthenticated = auth.user().onCreate(async (userRecord) => {
const adminFirestore = getFirestore();
...


package.json

"firebase-functions": "~6.3.1",


I'm importing the 'auth' like so:

import { auth } from 'firebase-functions';


...and getting the following error:

Module '"firebase-functions"' has no exported member 'auth'.
​

Any help greatly appreciated.
Thanks.
