[erlang-questions] Push a message to cowboy websockets

[Barco You]

thank you very much you all.

But next question: how can I delete a client from the broadcast pool,
because the gproc has only the API to unregister a process by "key" -
unreg(Key) - and can not find unregister by Pid().

Best regards,
Barco
