Installing and configuring subfission/CAS in Laravel 11

I am new to Laravel 11 and I see that quite a few things have changed compared to version 10. I'm not sure what to do because the Laravel 10 configuration form cannot be applied.

Does anyone have experience installing and configuring the subfission/CAS package in Laravel 11?

They haven't updated the documentation on Github and I'm a little lost.

Any suggestion or advice?
