For Angular12 / Firebase 9 / AngularFire 7 imports should looks like:

import firebase from 'firebase/compat/app';
import 'firebase/compat/firestore';

and then

fieldName : firebase.firestore.FieldValue.delete()

To use the FieldValue.delete() method you have to import:

import * as firebase from 'firebase/app';

or as camden_kid suggested:

import { firestore } from 'firebase/app';
