in 'cli-chat' example cli-chat.controller-behaviors.chat/update-user! function assigns 'loggable-user' in the 'channels' atom under the ':user' key so 'loggable-user' doesn't replace 'guest' in the channel.

When we call /me endpoint the response looks like this:

{:session-id #uuid "3dec53a7-0518-4912-b92a-7c5da257f5d4", :users/role :guest, :users/id #uuid "7701c8b3-2fe5-48ba-b428-954e59871544", :users/name "guest_OHAA", 
:user {:users/id 1, :users/name "enes", :users/role "member"}}

My suggestion is to change the (swap! channels update ch assoc :user loggable-user) in 'update-user!' to this:
(swap! channels update ch merge loggable-user) to resolve this problem.
