Thanks for getting back to me so quickly.
I think your answer is spot on, and that’s what I feared: I’ll have to create a small local interface that calls the Workflow via webhook. The thing is, that interface will never be as good as the one provided by the “When a chat message is received” node. Also, I’ll need to keep in mind that I’m using a Simple Memory node to maintain the conversation history, and I think I’ll need to somehow specify the session ID. Well, anyway. Thank you very much for your help.
