I’m developing a Teams bot app and need to retrieve chat history. I’m planning to use the Graph API endpoint chats/{chat-id}/messages. However, I need to know how to obtain the chat-id for this request. How can I get the chat-id?

public async Task OnMessageActivityAsync(ITurnContext turnContext, AppState turnState, CancellationToken cancellationToken)
 {
      

         string token = turnState.Temp.AuthTokens["graph"];
         var conversationReference = turnContext.Activity.GetConversationReference();
