ManagementApiClient missing FirstName LastName

I’m just adding things using the standard Auth0 interface to create a number of user with all associated details based on what eventually our organisation is going to be doing once the business has finally sorted out the requirements. I need to get things moving along so we don’t have to many delays, yet as details are still being ignored and fiddly aspects of business process are under consideration I can’t justify the business case for anything as complex as an actual running application.
So I can only configure Auth0 as much as possible using its own interface to cover a fully federated SSO authentication model using SAML with a couple of dozen test accounts with anticipated roles and special metadata attributes.
Some of the special metadata we will need is First Name, Last Name, and Middle Name, Roles, and additional special ones for various other integrations.

Now my Question is how do I show/demonstrate these in the User profile of Auth0 to Business people that do not care about or want to ever see any JSON?

It’s this demonstration that could convince them Auth0 is go enough for me to start cutting code on new applications and integrating with existing applications.
