In Laravel, How can I add an auto incrementing ID based on Pagination in Resource

Is there any way to display pagination incrementing id in Laravel which is sorted inside a Resource class?

I know I can do this easily in frontend, but I want to achieve this in backend.

This is my code in my controller and resource class.

//controller

$materials = MaterialResource::collection($items->paginate(6)->appends($request->query()));
return inertia('Admin/Material/Index', compact('training', 'materials'));

//MaterialResource

 public function toArray($request)
    {
        return [
            'id' => $this->id, //this can be 5,4,2,1 (order by title)
            'title' => $this->title,
            'tags' => $this->tags,
            'paginate_id' => 0, //this should be current_page + 1,2,3,4,5....
        ];
    }
