I currently added a new api resource for products (related to user model)

it actually works fine but the result that i retrieve from the POST request is

{
    "data": {
        "type": "user-products",
        "id": "10",
        "links": {
            "self": "/user-products/10"
        },
        "attributes": {
            "user_id": 1,
            "product_title": "Sample Product",
            "product_description": "This is a sample product description.",
            "product_price": "19.99",
            "currency": "USD",
            "status": "available",
            "createdAt": "2025-01-16T09:12:40+00:00",
            "updatedAt": "2025-01-16T09:12:40+00:00"
        },
        "relationships": {
            "user": {
                "data": {
                    "type": "users",
                    "id": "1"
                }
            }
        }
    },
    "jsonapi": {
        "version": "1.1"
    }
}

as you can see i get correctly the user relation, but i want also all the user data, not only the type and the id

here's my resource

public function model(): string
    {
        return UserProduct::class;
    }

    public function scope(Builder $query, OriginalContext $context): void
    {
        $actor = $context->getActor();
        $query->where('user_id', $actor->id);
    }

    public function endpoints(): array
    {
        return [
            Endpoint\Create::make()
                ->authenticated(),
            Endpoint\Update::make()
                ->authenticated(),
            Endpoint\Delete::make()
                ->authenticated(),
            Endpoint\Show::make(),
            Endpoint\Index::make()
                ->paginate()
                ->limit(30),
        ];
    }

    public function fields(): array
    {
        return [
            Schema\Integer::make('user_id')
                ->requiredOnCreate()
                ->writable(),
            Schema\Str::make('product_title')
                ->requiredOnCreate()
                ->writable(),
            Schema\Str::make('product_description')
                ->requiredOnCreate()
                ->writable(),
            Schema\Str::make('product_price')
                ->requiredOnCreate()
                ->regex('/^\d+(\.\d{1,2})?$/')
                ->writable(),
            Schema\Str::make('currency')
                ->requiredOnCreate()
                ->maxLength(3)
                ->writable(),
            Schema\Str::make('status')
                ->writable()
                ->regex('/^(available|sold)$/'),
            Schema\DateTime::make('createdAt'),
            Schema\DateTime::make('updatedAt'),

            Schema\Relationship\ToOne::make('user')
                ->type('users')
                ->includable()
        ];
    }

    public function sorts(): array
    {
        return [
            SortColumn::make('createdAt'),
        ];
    }

what im doing wrong?
