I'm trying to upgrade my app dependencies and my code, because I need this commit, so I edited my package.json and specified:

 "@angular/fire": "~7.1.0-rc.4",
 "firebase": "^9.0.0",

then I changed my imports from:

import { AngularFirestore } from '@angular/fire';

to

import { AngularFirestore } from '@angular/fire/compat';

My app is a Ionic5/Angular12 app, so I assume it uses Ivy by default. Looking here seems to me I've done everything that was needed to upgrade.

However I get the following compilation error:

 Module '"@angular/fire/compat"' has no exported member 'AngularFirestore'.ts(2305)
 import AngularFirestore

What am I missing?
