[Feature Request] More documentaion for new dash-auth 2.2.0 package #150

Dear,

I would like to request more documentation for the new version of Dash-Auth (version 2.2.0). The explanation of defining public routes and public callbacks is not clear in the current documentation. Although I have reviewed the documentation, it seems insufficient.

For example, I don't have public routes, but I do have some callbacks to open modals or new pages from a sidebar. I am encountering an error related to the line if inp["property"] == "pathname", and when I replace it with if isinstance(inp, dict) and inp.get("property") == "pathname", the issue goes away. However, I understand that modifying the library in this way is not the correct approach.

It would be immensely helpful to have additional examples for debugging purposes.

Thank you.
