I am trying to use the following formulas to auto-populate two text fields, First and Last name, for the user accessing a survey.
pulldata("@property", 'userFirstName')
pulldata("@property", 'userLastName')The doc here is where I pulled the formula. I can pull the email and username but not the first and last name. Survey123 Connect returns Unknown instead of the first and last name.

What formula do I use to pull the first and last name through Survey123 Connect?
