// Usage:
//   node TEST/testGooglePhotosAPI.js <ACCESS_TOKEN>
//   GOOGLE_ACCESS_TOKEN=ya29.xxx node TEST/testGooglePhotosAPI.js
//
// The token must have been granted the scope:

//
// Getting a token from OAuth Playground (https://developers.google.com/oauthplayground):
//   1. Click the gear icon → check "Use your own OAuth credentials"
//   2. Enter your Client ID and Client Secret from Google Cloud Console
//   3. In "Input your own scopes" enter:
//        https://www.googleapis.com/auth/photospicker.mediaitems.readonly
//   4. Click "Authorize APIs" and sign in with your test Google account
//   5. Click "Exchange authorization code for tokens"
//   6. Copy the Access token (starts with ya29.) and pass it here
