Hi Team,

I would like to receive the initial conversation start message created in Copilot Studio in C#. We use the DirectLineClient object to get the default message, but I'm not getting the conversation start message with the code below. The client.Conversations.GetActivitiesAsync(conversationId, watermark) call always returns null.

// Initialize Direct Line client
var client = new DirectLineClient(directLineSecret);
// Start a new conversation
var conversation = await client.Conversations.StartConversationAsync();

Console.WriteLine($"CoPilot ConversationId: {conversation.ConversationId}");

static async Task GetInitialBotMessageAsync(DirectLineClient client, string conversationId)
{
string watermark = null;
// Poll for messages, assuming the bot sends a message at conversation start
while (true)
{
var response = await client.Conversations.GetActivitiesAsync(conversationId, watermark);
watermark = response.Watermark;
foreach (var activity in response.Activities)
{
if (activity.From.Id == "bot")
{
Console.WriteLine($"Bot (Initial Message): {activity.Text}");
return; // Exit after getting the initial message
}
}
await Task.Delay(1000); // Wait before polling again
}
}

// Ysend a message to the bot if needed
var userMessage = new Activity
{
From = new ChannelAccount("user1"),
Text = "Hello, how can I help?",
Type = ActivityTypes.Message
};
await client.Conversations.PostActivityAsync(conversationId, userMessage);

// We are getting a success response for the message what we sent
var response = await client.Conversations.GetActivitiesAsync(conversationId, watermark);
