How to get chat id and chat name ?

[vitokorn]

Hello, can i get the chat or channel id and name by using tg.Entities or by using UpdateNewChannelMessage?
To get private channel id i use this:

dispatcher.OnNewChannelMessage(func(ctx context.Context, e tg.Entities, update *tg.UpdateNewChannelMessage) error {
  msg, ok := update.Message.(*tg.Message)
  if !ok {
    return nil
  }
  var re = regexp.MustCompile(`(?m)(\d+)`)
  var val string
  for i, match := range re.FindAllString(msg.PeerID.String(), -1) {
    val = match
  }
  return nil
})

But in examples i can't find how to get channel id for public channels. And my second question, is it possible to get dispatcher.OnNewChannelMessage works with selected chats like in telethon ?
@tclient.on(events.NewMessage(chats=chats))
