Personal/private accounts presence

Greetings,

We would like to know if personal/private accounts are also accessible through Shine API.

Do the TPPs have to do any additional steps (different options/headers/parameters, etc) in order to retrieve them?

Is it handled on bank's side and the user has only to insert his personal/private credentials? Or is there a separate endpoint or API for personal/private accounts?

Kind regards,
Anastasia
