can I override or add config files in my ThirdParty/package?

You would also need the email config file because Myth::Auth use it also.

I know this, I wonder if it is possible to do so as I wrote above.

or I think to do everything in APP and use to expand my mini CMS. https://codeigniter4.github.io/userguide...dules.html

And when someone gives my mini CMS, they will need to fill in the APP folder and the module folder

And when I do a new project I will need to fill in the APP folder and the modules folder
