Filling up relation Data from route and request

[ItsReddi]

Hi,
I am currently trying this package.
But have a tough time i tried to stick to the docs but i cannot get it to work.
I have a data class, with a relation in it:

        #[FromRouteParameter('someModel')]
        #[DataCollectionOf(PageData::class)]
        #[AutoLazy]
        #[LoadRelation('pages')]
        public Lazy|array $pages,

i want it only loaded if the parameter is included so:

public static function allowedRequestIncludes(): ?array
    {
        return [
            'pages',
        ];
    }

Controller:

public function getContent(MyData $data): Data 
{
    return $data;
}

Route:
Route::get('/someModel/{someModel}', [ModelController::class, 'getContent']);

Request:
$this->getJson("/api/v1/someModel/{$someModel->id}?include=pages")

The issue i have now is that it does not return a collection of PageData but the complete eloquent models. (for that i have to change the type to mixed, otherwise i just get a 422 validation error).

I also tried without autolazy doing that myself in fromModel but the fromModel method is not even called.
May i am using it entirely wrong, any advice how to archive my goal?
