Slim 4 with Authentication (but at php 8+ level)

Hi Alex. I have worked on your Slim 4 Authentication course incorporating Sentinel. I struggled with a lot of dependency issues. Would it be possible to upgrade this to work with the latest php version 8 (and dependencies that support thiis)? I have been digging around Daniel Opitz's Slim 4 skeleton and his supporting 3 Slim 4 books and it seems to me that the only thing that is missing is the incorporation of a Sentinel like authorization system which your course handles really well. Someone I spoke to said that PHPAuth may be a better (more up to date Auth framework if Sentinel is outdated). I know Daniel deals with simple authentication but he has none of the login forms etc. which Sentinel has. Anyway, just an idea to consider as a course I would totally love to participate in (as I am trying to pin down Slim 4 with DI Containers etc. in Slim 4 which his baseline seems to be a good standard).
