i just changed the developerKey and clientId. upon testing, a popup showed to choose which google account should i use. after that, it showed a popup again for me to allow my application to access the drive. after clicking the allow button. nothing happened. popup closed. no message in console.

here is the link https://developers.google.com/picker/docs/#hiworld

You also need to enable Google Picker API on your project:

1. Go to https://console.cloud.google.com/apis/dashboard?project=YOUR-PROJECT-NAME
2. Click on "ENABLE APIS AND SERVICES"
3. Search for "Google Picker API"
4. Click "ENABLE"

Now it should open the Google Picker correctly.

I hope it's clear!
