Format pagination metadata for all collections (API)

Hello, I'd like to format the pagination of all my Api Resources without having to create a "Collection" class for each Model.

I'd like to do it like this:

class UserCollection extends ResourceCollection
{
    public function toArray($request)
    {
        return [
            'data' => $this->collection->transform(function (User $user) {
                return new UserResource($user);
            }),
            'meta' => [
                'total_users' => $this->collection->count(),
            ],
        ];
    }
}

For User, Post, Category models, etc...

Do you have any ideas? Thank you!

I tried this, but it does not work :

class GenericCollection extends ResourceCollection
{
    protected static $resourceMap = [
        Category::class => \App\Http\Resources\CategoryResource::class,
        User::class => \App\Http\Resources\UserResource::class,
    ];

    public function toArray($request)
    {
        return [
            'data' => $this->collection->transform(function ($model) {
                return self::getResourceClass($model);
            }),
            'foo' => 'bar',
        ];
    }

    protected static function getResourceClass($model)
    {
        foreach (self::$resourceMap as $modelClass => $resourceClass) {
            if ($model instanceof $modelClass) {
                return $resourceClass;
            }
        }

        throw new Exception('Resource class not found', 500);
    }
}
