How to Read Private Files on Google Cloud Storage

  google-cloud-storage, laravel, php

I want to create a media storage apps, that allows user to upload and view their media on my platform.
I use laravel to create it.
I was successfully upload it to google cloud storage with private file attribute, and save the file name to my database.

My question is, how to access it directly from the laravel, and show it as image or video, currently I have cide.json file as a key, but I never get detail explaination how to use it.
