is there a way to implement group chat to "Ai Character Chat ?“

I've been quite enjoying AI Character Chat, for me it's so facinating to have ChatGPT like ai but with uncensored data and i can see Ai Character Chat capable doing that easily.
But the real pain is when i introduce additional character to same chat thread (e.g. i use default character named Chloe and then i add new character to same chat thread) and the additional character can't auto reply to user or original character in chat, so my question is can we make additional character in same chat thread have auto reply function same like the default character ?

Sorry for bad English, i've hard time to explain it in propper way
