ChatGPT reviews recent chats, lists the unanswered ones and missing answers, and fills them in once you reply.

There's no separate setup per channel or per app: one MCP server covers them all.
What is ChatGPT?
ChatGPT is OpenAI's AI assistant, on chatgpt.com and in the desktop and mobile apps.
Custom MCP servers let ChatGPT use the tools of other apps. Add Chatfuel, and it can set up your AI Agent and work with your chats from the conversation.
