Laravel DDD Pattern (Repository and Service)

I'm working on the laravel pattern, I will have questions in a few places.

I am doing a simple insert operation

PostController

 public function store(StorePostRequest $request): JsonResponse
  {
    return $this->postService->store($request);
  }

PostService

public function store(StorePostRequest $request): JsonResponse
    {
        DB::beginTransaction();

        try {

            $post = new Post();
            $post->uuid = Str::uuid();
            $post->title = $request->input('title');
            $post->description = $request->input('description');
            $post->status_id = $request->input('status_id');
            $post->created_by_user_id = Auth::id();

            $this->postRepository->store($post);

            DB::commit();

            return response()->json(['status' => true, __('service.the_operation_was_successful')]);
        } catch (Exception $exception) {
            DB::rollBack();
            return response()->json(['status' => false, __('service.error_occurred_during_operation')], 500);
        }
    }

PostRepository

public function store(Post $post): Post
 {
   $post->save();

   return $post;
 }

My main question is: Should I move the try cacth block to the controller side? To make the service side look cleaner. If I move, how can I do DB::beginTransaction() transactions, can you help and share your ideas?
