@Chowderr Could you help me understand what happens when we use Background Messaging please?

Log the Action as a System Message
When the button is clicked, the logUserAction function will silently insert a system message into the chat history:

function logUserAction() {
  // Function to log the user action
  vapi.send({
    type: "add-message",
    message: {
      role: "system",
      content: "The user has pressed the button, say peanuts",
    },
  });
}

Claude only allows one system instruction, you can't insert a system message in the middle of the conversation history. So is Vapi adding this to the main system message? Thank you!
