The best way to incorporate access control for application features is with Laravel’s Model Policies.
Using Policies allows you to simplify things by abstracting your “control” rules into one place, where your application logic can be combined with your permission rules.
Jeffrey Way explains the concept simply in the Laravel 6 Authorization Filters video and some related lessons in that chapter. He also mentions how to set up a super-admin, both in a model policy and globally in your application.
You can find an example of implementing a model policy with this Laravel Permissions package in this demo app: https://github.com/drbyte/spatie-permissions-demo/blob/master/app/Policies/PostPolicy.php
