Hey everyone, I'm curious about the capabilities of chatbots in terms of memory and session persistence. Specifically, can a chatbot remember a conversation and retain information about the user who initiated the chat after the session has been closed? If so, what's the typical duration for a session memory? And importantly, does this capability extend to channels like WhatsApp and Messenger, or is it limited to webchat platforms? I'm looking into developing or integrating a chatbot that can provide a more personalized experience by recalling previous interactions, even after some time has passed since the last conversation. Any insights or experiences with different platforms that support these features would be greatly appreciated. Thanks in advance for your help!
