    Class Mem0Memory

    Class used to manage the memory of a chat session using the Mem0 service. It handles loading and saving chat history, and provides methods to format the memory content for use in chat models.

    const memory = new Mem0Memory({
      sessionId: "user123" // or use user_id inside of memoryOptions (recommended),
      apiKey: "your-api-key",
      memoryOptions: {
        user_id: "user123",
        run_id: "run123"
      },
    });

    // Use with a chat model
    const model = new ChatOpenAI({
      model: "gpt-3.5-turbo",
      temperature: 0,
    });

    const chain = new ConversationChain({ llm: model, memory });
