AI Chatbot doesn't re-initiate after a conversation with a Human

When I request to chat with a human through the AI chatbot, the bot does not reengage after I mark the ticket as closed. After resolving the ticket and closing the bot window, attempting to start a new conversation with the bot leads to the reopening of the previous ticket rather than initiating a new session with the AI assistant.

I’m unsure how to properly restart the AI chatbot after a successful human interaction. Ideally, each time a customer chats with a human, a new case should be opened.
