I have creator app that internal staff use to record training, I need to be able to pull a first name and surname from their ZohoOne profile when selecting them via a dropdown.

The only fields I seem to be able to fetch are : username, email address and role.

How can I select a user from a drop down and show their first name in another input field.

* it will not always be the logged in user performing the lookup so using the loggedinuser for looksups won't apply
