not getting correct \Spatie\Permission\Exceptions\UnauthorizedException thrown

[some0ne2]

I'm using this wonderful package with permissions only, as documentation is recommending to do.

app/Policies/OrderTransactionPolicy.php:

namespace App\Policies;

use App\Models\User;
use Illuminate\Auth\Access\HandlesAuthorization;

class OrderTransactionPolicy
{
    use HandlesAuthorization;

    /*
        order policy is auto discovered by laravel
    */

    public function view(User $user)
    {
        return ($user->can('view order transactions'));
    }
}

Inside my controller action I use:

 $this->authorize('view', OrderTransaction::class);

When I try to visit a protected controller action as a user without required view permissions I get (debugbar):

This action is unauthorized.

.../vendor/laravel/framework/src/Illuminate/Auth/Access/Response.php#119

Using dd($exception) directly inside the Handler shows:

Illuminate\Auth\Access\AuthorizationException {#1911 ▼

I thought this might throw an \Spatie\Permission\Exceptions\UnauthorizedException exception.
Am I using the package correctly or why isn' this exception thrown?
I would like to implement a custom view to be rendered for this exception.
