[khristina91]

` private async Task AddUserToChannel(TelegramClient client, TLUser user, int channel_id) { //channel_id is the destination group

  var request = new TLRequestAddChatUser
  {
    ChatId = channel_id,
    UserId = new TLInputUser() { UserId = user.Id, AccessHash = user.AccessHash.Value },

Use a valid group ID and it would work.
