Table for Names details in Usernames page for External users

We have a requirement to pull all External user's usernames (users without person record) with other details like FirstName, LastName and Email displayed in "User Information" section on Security Console - Users Page

Could you please share the query or tablename where this First name, last name and email address are stored.

As these external users don't have person record attached, there is no record in per_person_names_f table or per_email_addresses table.
