policy doesn't working in laravel in module - laravel-8

Question

this is my Auth Service Provider :
<?php
namespace App\Providers;
use App\Models\Profile;
use App\Policies\ProfilePolicy;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use RequestManager\Http\Models\RequestState;
use RequestManager\Policies\RequestStatePolicy;
class AuthServiceProvider extends ServiceProvider
{
protected $policies = [
Profile::class=>ProfilePolicy::class,
RequestState::class=>RequestStatePolicy::class,
];
public function boot()
{
$this->registerPolicies();
}
}
this is my policy array :
array:2 [
"App\Models\Profile" => "App\Policies\ProfilePolicy"
"RequestManager\Http\Models\RequestState" => "RequestManager\Policies\RequestStatePolicy"
]
I have a policy that is in its own module folder with this structure :
this is my controller :
public function showDepartmentRequests($id)//id = department id
{
$request=RequestState::where('department_id',$id)->get();
dd(\Gate::forUser(User::find(2))->allows('view',$request));
}
and this is my policy :
<?php
namespace RequestManager\Policies;
use RequestManager\Http\Models\RequestState;
use App\Models\User;
use Illuminate\Auth\Access\HandlesAuthorization;
class RequestStatePolicy
{
use HandlesAuthorization;
public function view(User $user, RequestState $requestState)
{
dd("test view policy");
}
}
Nothing is printed when I call the gate!
Is this error because I have to register a policy within a specific auth service Provider
other than the app\AuthServiceProvider?
