    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ message }),

  if (!response.ok) {
    console.error("Failed to interact with the agent:", response.statusText);
    return;
  }

  const data = await response.json();
  console.log("Agent Reply:", data.reply);
}

interactWithAgent("Aura", "Hello there!");
