Google owns YouTube, so it's a pretty safe assumption on Google's end that
it's OK to share account information with YouTube. So there's no
authorization window on YouTube.

But Google doesn't own your application, so before sharing account
information with your application Google needs to warn the user and make
sure the user opts-in to authorize your application. So there's a
permissions window before granting account access when your app implements
the oauth flow.
