Laravel Filesystem: Managing Folders in Google Drive API

I am following this tutorial:- https://gist.github.com/sergomet/f234cc7a8351352170eb547cccd65011

My Laravel application requires files to be organized inside a folder. So, whenever a file is uploaded it should be saved inside a folder that it belongs to.

Before uploading a file, I must check whether the folder exists or not. In Laravel, I have used this method to list all the directories at root.

$directories = Storage::directories();

However, it returns a list of alphanumeric unique ids with no references to the human readable names. I don't want to create duplicate folder even though it is possible in Google drive.

So, how do we get list of folder names along with reference id?
