Backup of Firestore like in Firebase Realtime Database?

Question

I'm looking for a way to backup in Firebase Firestore. I found https://firebase.google.com/docs/database/backups but this is for the Firebase Realtime Database.

I can't seem to find documentation on an equivalent way to backup for Firestore.

There are manual ways to backup such as described in https://medium.com/@BrodaNoel/how-to-backup-firebase-firestore-8be94a66138c.

But I'm looking for a GCP equivalent before making my own process.
