News Streams configuration.

Hi ,

I am trying to find how News stream feature on Jive 9.X works. I am trying to create one as mentioned here. I see when we create a news stream from News page we can assign it to specific people/security groups and, also push the content/container in the stream.  Where can I find these stream specific details (people,security groups,content/container) in the Db ? I check in jivestreamconfiguration table but, doesn't seem to be there.

Just wanted to check before I start digging code. 

Thanks in advance.
