Help need for composer package

Hello,

I'm starting a simple composer package for ci4 : https://github.com/bvrignaud/ci4-admin
The goal is to have a simple admin panel.
It's base on Ion-Auth and AdminLTE.

I'm noob with create composer package.

I have some problem with the views.
I'm unable to load views in the Controllers.
I think it's a problem with the namespace declaration in composer.json.

Have you an idea please.

Thanks
