I am building a chat application using botframework v4 with .net core. I want to implement customized typing indicator. Currently I am using below code and it is showing typing indicator like below image.
public async override Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default)
ITypingActivity replyActivity = Activity.CreateTypingActivity();
await base.OnTurnAsync(turnContext, cancellationToken);
But instead of showing this typing symbol(...), I need to show some customized message (like bot is typing) and after getting bot response indicator need to remove automatically.
