Get the ftp upload percentages with Laravel FileSystem

Hello guys, so i have an app like wetransfer.com, so i'm trying to get the upload percentage from the ftp.

Here is my upload controller.

  public function upload(UploadRequest $request)
    {
        /*
         * If user have registration, make his own folder with name of his email address
         */
        $folder = !Auth::user() ? md5(Str::random(10) . $request->ip() . time()) : Auth::user()->email;

        // Get all of the files
        $files = $request->file('cloudesk_upload');

        // Generate Short url
        $shortUrl = env("SHORT_URL") . "/" . Str::random(5);

        /*
         * Generate a new short link
         */
        $link = new Link();
        $link->url = $shortUrl;
        $link->save();


        /*
         * Data insert
         */
        $data = [];

        foreach ($files as $file) {
            $filename = md5($file->hashName());
            $data[] = [
                "original_name" => $file->getClientOriginalName(),
                "unique_name" => $filename,
                "last_modified" => time(),
                "server_path" => env("UPLOAD_MAIN_DIR") . "$folder/$filename",
                "size" => $file->getSize(),
                "extension" => $file->getClientOriginalExtension(),
                "in_dir" => $folder,
                "link_id" => $link->id,
                "delete_at" => Carbon::now()->addWeek(1),
                "user_id" => Auth::user() ? Auth::user()->id : null
            ];

            Storage::disk('fu_ftp')->put("home/" . "$folder", $file);
        }

        File::insert($data);

        return response()->json([
            "success" => "file was uploaded successfully",
            "file" => $data,
            "url" => $link->url
        ], 200);
    }

And my front end side:

   const onDrop = useCallback(acceptedFiles => {
        setShowUpload(false);
        const uploading = acceptedFiles.map(file => {

            console.log(file);

            const formData = new FormData();
            formData.append("cloudesk_upload[]", file);
            const xhr = new XMLHttpRequest();
            xhr.upload.onprogress = event => {
                const percentage = parseInt((event.loaded / event.total) * 100);
                setUploadPercentages(percentage);
            };
            xhr.onreadystatechange = () => {
                if (xhr.readyState !== 4) return;
                if (xhr.status !== 200) {
                    console.log('error'); // Handle error here
                }
                console.log('success'); // Handle success here
            };

            setTimeout(() => {
                xhr.open('POST', `${window.API_URL}/upload`, true);
                xhr.send(formData);
            }, 3000)
        });
    }, [])

It's work but just show the percentage of how many form data is sended to the backend.

How to get how many of that file are uploaded to the ftp. Thank u in advice :)
