3. Configure an OAuth consent screen (“internal” is fine for testing)
4. Add scopes https://www.googleapis.com/auth/tasks
5. Create an OAuth Client ID for application type “Desktop App”
6. Download the JSON file of your client’s OAuth keys
7. Rename the key file to gcp-oauth.keys.json and place into the root of this repo (i.e. gcp-oauth.keys.json)

Make sure to build the server with either npm run build or npm run watch.
