Thanks @NateDhaliwal!
The chat screen (on the right hand side of the screen) will be present on topic load. Meaning it will be there whether a user is “going” or not. The user is granted access to the chat channel once they select “going”, which also updates the chat channel by removing a CTA blocking the input to message (for non “going” users).
Currently, yes.
Currently, the channel is neither deleted nor closed after the livestream has ended or the livestream topic was closed.
