How can I send mediaGroup with uploaded files (no public url allowed, signed urls is not an option)

[czernika]

inputMediaPhoto allows you to attach media files using attach:// keyword. How can I send multiple photos from local storage (not publicly accessible, not S3). Basically, I need to provide path to file in order for telegram to upload it (same way as photo does) but for multiple instances

$max = 10;
$photos = $galleryPhotos->when($galleryPhotos->count() > $max, function ($collection) use ($max) {
            return $collection->random($max);
})->map(function ($photo) {
            return [
                'type' => 'photo',
                'media' => 'attach://' . $photo->hash,
            ];
});

$this->chat->mediaGroup($photos->toArray())->???->send();

I guess I need to pass every photo hash into data (using withData?) array with uploaded file content, but I couldn't figure it out, how to chain methods properly. I need to access file property of telegraph class and I see no way how can I achieve this

Thanks in advance

Was able to achieve this by overriding proivder

// AppServiceProvider

public function register(): void
    {
        $this->app->bind('telegraph', fn () => new CustomTelegraph);
    }

// CustomTelegraph

<?php

declare(strict_types=1);

namespace App\Services\Telegram;

use DefStudio\Telegraph\DTO\Attachment;
use DefStudio\Telegraph\Telegraph;

class CustomTelegraph extends Telegraph
{
    public function withFile(string $key, string $path)
    {
        $telegraph = clone $this;

        $this->files->put($key, new Attachment($path));

        return $telegraph;
    }
}

// handler

$max = 10;
        $photos = $galleryPhotos->when($galleryPhotos->count() > $max, function ($collection) use ($max) {
            return $collection->random($max);
        });

        $request = $this->chat->mediaGroup($photos->map(function ($photo) {
            return [
                'type' => 'photo',
                'media' => 'attach://'.$photo->hash,
            ];
        })->toArray());

        foreach ($photos as $photo) {
            $request->withFile($photo->hash, Storage::path($photo->physicalPath()));
        }

        $request->send();
