To authenticate a Google Drive element instance you must have a project withe the Google Drive API enabled.
To set up the API Provider:
Navigate to your Google Drive developer dashboard and select your Google Drive project.
Enable the Google Drive API for the project. You are free to enable other APIs as well, but we require at least the Google Drive API.
After you enable the Google Drive API, click Credentials on the left-hand side ,and then click Create credentials.
Select Web Application as the Application type and follow the prompts.
Note the OAuth client secret and OAuth client ID, which you need to authenticate an element instance.
