How to resolve a class from a router / controller? (Similar to Eloquent API Resources)

I'm looking for a way that works similar to Eloquent API Resources. Unfortunately, my brain doesn't comprehend the magic behind it.

Similar like here:

use App\Http\Resources\UserResource;
use App\Models\User;

Route::get('/user/{id}', function ($id) {
    return new UserResource(User::findOrFail($id));
});

I want to use

use App\Http\Recommendations\RecentlyUpdatedRecommendation;
use ...

Route::get('/someurl', function () {
    return ['collections' => [
       new RecentlyUpdatedRecommendation(),
       new WatchlistRecommendation(),
       new LastWatchedRecommendation(),
       ...
    ]];
});

What can I do to get that syntax?

Ok I found some help! I leave this post be, maybe it's helpfull as well:

 abstract class Recommendation implements Arrayable, JsonSerializable {
  
 }

...

class SomeRecomendation extends Recommendation {

 public function jsonSerialize()
  {
    return $this->toArray();
  }

  public function toArray(){
    return [
      'title' => $title,
      'description' => $description,
      'courses' => (collection) $courses
    ];
  }
}

Now watch will happen, When you return ['collecion' => new SomeRecomendation()], Laravel calls json_encode on it ( to return response as json ), Because new SomeRecomendation() is instance of JsonSerializable it will call jsonSerialize method and encodes an array returned from it.
