While in PandaDoc, you can visit your Account settings, and navigate to Team.
Once you have confirmed that they are a seat in your account, the account Administrator can visit notarize.pandadoc.com to invite that user to be the notary.
Click +Invite a Notary at the top right. After this, the individual will receive an email to activate their notary account.
