short chat with the user without exiting the graph

[wisefinger]

I have a use case where I need to create a complex graph. In some cases in the middle of the graph, I want to ask a few ad-hoc questions to the user, and then continue the graph. I have found examples of human-in-the-loop solutions but they are oriented on getting approval. In my case, I want to ask some questions and then continue. Does anyone has ideas on how this can be tackled? I can persist the state and then load it into a new invoke of the graph but that is not a performant solution

I usually use a pattern like this: https://langchain-ai.github.io/langgraph/how-tos/human_in_the_loop/wait-user-input/
