As i have understood, the current bots provided by the AI plugin are able to talk through PM’s but not through chat. However, they do have chat enabled in their profile, so you can open a chat conversation with them, which they will not respond to.
Agree we should suppress.
I have such mixed feelings around enabling ai bot on chat. It makes auditing so much more complicated, and starting new conversations is not trivial.
The one exception is that I want an AI Copilot sidekick for a topic, so you can chat with an existing topic.
