i'm quite new to Firebase and currently having some trouble trying to implement a custom role for my project. Is there a way to set a role with only Database permissions (add and delete) and another one responsible only for Authentication? Thanks in advance!

You'll note that the database role is still less granular than what you want, you can simply allow the user to edit the database or not.
