I'm trying to configure Google's Identity Toolkit API, however I'm unable to figure out why my Widget URL is empty and, actually, I don't know where I can register these Widget URLs.
I'm really confused, because Google's documentation (Identity Toolkit for Websites) is showing how to set up things in the new UI, but every time I open the developer console (console.developers.google.com) I get the old interface, which does not match the explanation.
