How to send system prompt into a chat

[dizzyn]

Hi, thank you for you work.

Q: Is there please a std. way how to pass initial system prompt into configured chat:

const chatBot = ax`
  message:${f.string("A casual message from the user")} -> 
  reply:${f.string("A friendly, casual response")}
`;

Some thing like:

 let response = await chatBot.forward(ai, [
      {
        role: "system",
        message: systemPrompt,
      },
      ...chatHistory,
    ]);

But the system prompt

1. doesnt match the structure (is not casual and is not from the user, doesnt need response)
2. and is not valid typescript (Type '"system"' is not assignable to type '"user" | "assistant" - The expected type comes from property 'role' which is declared here on type 'AxMessage')
