Default function to get download URL for uploaded recent image - Firestore storage - PHP LARAVEL

I have written my code by following this URL:

https://laravelwithfirebase.blogspot.com/2020/07/chapter-19-how-to-upload-image-to-firebase-storage-from-laravel-php.html

The image is successfully uploaded.

But now, how I can call getDownloadURL() function for current uploaded image from $imag variable. I have mentioned it below.

$image = app('firebase.storage')
            ->getBucket()
            ->upload($uploadedfile, ['name' => $firebase_storage_path . $file]);
