title: telegram bot can't send messages to super group
body: <p>this is my code</p>
  
  <pre><code>private async void Bot_OnMessage(object sender, Telegram.Bot.Args.MessageEventArgs e)
      {
  
          var message = e.Message; if (message == null || message.Type != MessageType.Text) return; await Bot.SendTextMessageAsync(message.Chat.Id, "Hello?");
  </code></pre>
  
  <p>in this case, it works well with super groups</p>
  
  <p>but 
      await Bot.SendTextMessageAsync([supergroup chat id], "Hello?");</p>
  
  <p>put Super Group ID in here[supergroup chat id], it won't work.
  I've set up all the group permissions.
  After upgrading the super group, I had to drop the bot and invite again</p>
