List of custom field

You can use the user() function. Here I'm getting Custom Field 3 from the logged in user:

fn!user(fn!loggedInUser(),"customField3")

Thanks!, but I want it for all the users. No specific user.

Then iterate through your list;

a!localVariables(
  local!users: {
    touser("lily.fraser"),
    touser("admin.user"),
    
  },
  {
    a!forEach(
      items: local!users,
      expression: a!textField(label: fn!user(fv!item, "customField3"), readOnly: true)
    )
  }
)
