Looking at the PingCRM example Inertia repo. What is `through()` here? github.com/inertiajs/pingcrm/blob/0a798fadc87dc1cf22933bb1224c834df53579f5/app/Http/Controllers/OrganizationsController.php#L24

I can't find a reference in the Laravel or Inertia docs. Is it just a way of mapping the objects to an array? If so, what's the advantage over `only()`?
