How to implement a nav with navigation 3?

I'm making this post because I want to know how to implement Navigation 3 at the next scenario:

I would like to have like this (Is an example):

The navigation for Authentication like login, recovery, signup
The navigation for Main (with a bottom bar) like Home, Statistic
The navigation for Profile with their own screen, and with not the main bottom bar

Idk if I'm explaining alright or not :(

I'm Sorry!
