Hi to everyone, there is a function in Appian that let me get the username

Hi to everyone,
there is a function in Appian that let me get the username for a user starting from his Name Surname. I explain better, i have a cdt with a field (Name) in which i save the name and the surname of the user (for example Marco Cuva), I want to get the username in appian associated to that user and using the user to get his email.
PS: We use Appian 7.6
Thanks
