Using your own OAuth client

The plugin comes with it's own OAuth Client ID for ease of installation, but you can substitute your own if required (e.g. your organization has OAuth policy restriction on external apps). To do this go to the Google API Console and create a set of OAuth 2.0 credentials using the type "Other" and make sure to whitelist the scopes .../auth/cloud-healthcare and .../auth/cloudplatformprojects.readonly. Then download the credentials files in JSON format, name the file client_secrets.json and move it to conf folder, next to the ext-config.properties file.
