Lack of firestore features

Hey @Flavio_Bosco!

Can you try the following?

await db
  .firestore()
  .collection("testCollection")
  .doc("your_doc_id")
  .update({ your_field_key: firestore.FieldValue.delete() });

You should also be able to reference firestore.FieldValue.serverTimestamp() in raw queries as well @gcardwel!
