Enabling a connection to Google Drive requires the creation of an OAuth 2.0 Client ID through the Google API dashboard. 

Steps to Enable

• Follow the steps at https://developers.google.com/identity/protocols/oauth2 to create an OAuth 2.0 Client ID for your Avalon instance
• Use the Client ID and secret in your Avalon site's settings.yml (see Upgrading Avalon 7.2 to Avalon 7.3 for config details)
• Once configured, restart the app
• Google Drive will now appear as a source in the "Open Dropbox" file picker in Avalon
  • For instructions, see Connecting to Google Drive
