Laravel policies with middleware not working

Question

I'm building a website in Laravel. I'm trying to allow the view/modification of a Model only to the user that created it. I registered the policy and use a middleware in the route to restrict the view/modification/delete/update operations but I'm always unauthorized.

TrashPrivateReportPolicy:

class TrashPrivateReportPolicy
{
    use HandlesAuthorization;

    public function before(User $user){
        if($user->can('manage_all_projects')){
            return true;
        }
    }

    public function results(User $user, TrashPrivateReport $trash_private_report){
        return $user->reports()->map(function($report){$report->trash_report();})->contains($trash_private_report);
    }
}

AuthServiceProvider

class AuthServiceProvider extends ServiceProvider
{
    protected $policies = [
        //'App\Model' => 'App\Policies\ModelPolicy',
        'App\TrashPrivateReport' => 'App\Policies\TrashPrivateReportPolicy',
    ];

  
    public function boot()
    {
        $this->registerPolicies();

        Gate::before(function($user,$ability){
            return $user->abilities()->pluck('name')->contains($ability);
        });

    }
}

routes: web.php

Route::get('/trash_private_reports/results/{trash_private_report}','TrashPrivateReportController@results')->name('trash_private_reports.results')->middleware('can:results,trash_private_report');

So when I'm connected as a lambda user and want to see the page results
'/trash_private_reports/results/id/' access is forbidden. The policy does not seems to be called. I tried dd(..) in the method of the policy and nothing happens.

I have already tried:

Changing the policies array to:

TrashPrivateReport::class => TrashPrivateReportPolicy::class

Updating and clearing:

composer dump-autoload

php artisan route:clear

php artisan view:clear

php artisan config:clear

Thank you for the help :)

Edit:

I solved the problem by replacing before by after

Gate::after(function($user,$ability){
            return $user->abilities()->pluck('name')->contains($ability);
});
