User Criteria Catalog Item

[Tomas Linde]

Hello everyone,
I have created this User Criteria to prevent access to all users who contain the keyword "Manager" in their first and/or last name, it works for me but I also need it to prevent me from selecting this type of user in a variable of type reference to the "sys_user" table of my catalog item, any ideas (it's my first time using User Criteria).
Greetings and thank you.

function evaluateControl() {

  var user = new GlideRecord('sys_user');
  user.get(gs.getUserID());

  var firstName = user.getValue('first_name');
  var lastName = user.getValue('last_name');

  firstName = firstName.toLowerCase();
  lastName = lastName.toLowerCase();

  var containsManager = firstName.indexOf('manager') !== -1 || lastName.indexOf('manager') !== -1;

  if (containsManager) {
    return false;
  }

  return true;
}

I see...in that case, I'd recommend trying the other approach ->> replace the field on the catalog item with the "request for" type instead of a reference field to sys_user.
