Hook would be a great feature

[Kare-Udon]

Hi, thanks for your hard work!
I think adding hook features, execute commands at certain events, would be quite useful.
Like when codex needs user to respond, or the process is finished, users can play sounds or send notifications.

+1 on this feature. Would be quite useful to play a sound when the model finishes its response, which usually takes quite a long time.
