What does the notarize process mean in CKGS passport renewal process?

The checklist for the documents asked me to notarize the Valid i 797, Proof of residence and Change of Appearance form. It says " Notarized (with Stamp and Notary Signatory)". I get that I need to get it stamped from Notary. What does Notary Signatory means? Do I have to sign in their presence or they will sign the forms?

Notary has to sign and along with their official stamp.
