Video download api google drive, php javascripts

Good morning, I need a little special help.

I have a need with the google drive api, but I have no experience with it

I need to put on a website, a direct link to download files from google drive, that is, a button, that when pressed automatically starts the download if you leave the web.

The web application is based on php, html, and javascript

Can you help me a little to guide me? I’m very new to this api and I don’t understand it at all…

And I would like that you will not need oauth to authenticate, just the button to download

Thanks…
