I need to create a new public hangout with my app included. I do not want to use their JS api, so I just redirect user to the following URL:
https://plus.google.com/hangouts/_?gid=(my-app-id)
It works great with one exception - the newly created hangout is private and requires invitations. I want to make it "public" - so anyone with the link may join it. How do I do it?
