Para vc não precisar fazer um loop nas suas permissões :p

AuthServiceProvider.php

<?php

namespace App\Core\Providers;

use Illuminate\Contracts\Auth\Access\Gate as GateContract;
use Illuminate\Support\ServiceProvider;
use App\Domains\Users\User;

class AuthServiceProvider extends ServiceProvider
{
    public function boot(GateContract $gate)
    {
        $gate->before(function ($user, $permission, $args) use ($gate) {
            // GATE not have this ability
            if ($user instanceof User && !$gate->has($permission)) {
                // return $user->canDo($permission)
            }
        });
    }
}
