firebase - Firestore Security Rules: If timestamp (FieldValue.serverTimestamp) equals now

Question

How do I check if user on client sided created document with only firebase.firestore.FieldValue.serverTimestamp()?

I have following:

allow create: if request.resource.data.timestamp == ??

What should I have instead of ??. I have tried serverTimestamp() firebase.firestore.FieldValue.serverTimestamp(), now or now() but it doesn't work.

It is possible to do it in Firebase like this:

".validate": "newData.child('timestamp').val() === now"

I am looking for the same solution. Any ideas? Thanks
