Modify Laravel built-in Auth for users

I am using Laravel built-in Authentication for users which I run from the terminal php artisan make:auth

It has one table in the database, users table and has an isAdmin column, so I am assuming it has two roles an admin and not_amin account.

Now, what I want is to modify this built-in functionality of Laravel make:auth to be able to add some roles like isEmployee and/or isCustomer.

How can I achieve this using the available option I have? I hope, I somewhat explained my case. Thanks.
