Question for Notaries: Is document eligible to be notarized? (New York State)

I have a baptismal record for my great-grandfather from a Church in New York State. It is literally just a photocopy of a baptism register. I ultimately need the document notarized, so it can be approved by the county and then apostilled by the state.

The state of NY notarization form i believe is this: https://dos.ny.gov/system/files/documents/2021/03/2091.pdf

Question: For this to be allowed to be notarized as a true copy: Do i need someone from the church to sign the notary affidavit as the affiant? Or can i sign the affidavit as the affiant?
