Type hinting a service class in a Laravel model's constructor

In my Contact model, I’m trying to type hint a service class:

use AppServicesContactService;
class Contact extends Model
{
    /**
     * @var AppServicesContactService
     */
    protected $contactService;

    public function __construct(ContactService $contactService)
    {
        $this->contactService = $contactService;
    }
}

use AppServicesCRMCRMService;
class ContactService
{
    public function __construct(protected CRMService $crmService)
    {}
}

I’m getting this error:

Too few arguments to function AppModelsContact::__construct(), 0 passed in

The error happens when I call $dealer->contacts

public function contacts()
{
   return $this->hasMany(AppModelsContact::class, 'dealer_id');
}

I thought the $contactService should be injected automatically and I shouldn’t be including it manually. What am I missing?

    Based on the comments and answers, I ended up changing my Contact's model constructor to this and it's working great:

    use AppServicesContactService;

class Contact extends Model
{
    public function __construct()
    {
        $this->contactService = app(ContactService::class);
    }
}

    Thanks!

    Try this in Dealer class

    public function contacts()
{
    return $this->hasMany(
        AppModelsContact::class, 
        'dealer_id'
    )->setFactory(function ($attributes) {
        return app(Contact::class, [
            'contactService' => app(ContactService::class)
        ]);
    });
}
