Customizing Data Retrieval in Laravel Breeze Authentication for Custom Guard

I am using Laravel 10 with Laravel Breeze authentication and have implemented a custom guard named "members" for the "members" table, which includes 20 columns, including "email" and "password". After a successful login, the authentication system retrieves all data from the "members" table. However, I want to customize this behavior to retrieve only specific columns.

I have already explored using the "hidden" property in the model to hide certain columns, but I specifically want to select and retrieve data from specific columns. How can I achieve this customization in Laravel Breeze authentication with a custom guard?
