How To Add Google Drive Addon

So I have installed the Google Drive Add-On and I am trying to link to my Google Drive account. I have an API key made, and an OAuth Client ID/Secret Key made. What would be the authorized JavaScript origin? Because with what I have done already, I try to add a file from google drive, but I get the pop-up window that says that the JavaScript Origin does match the authorized ones for the OAuth Client. A screenshot of the error is attached to this.
