answer – command in tech channel which taking 3 arguments and writing like “/answer 1 <any text/text+photo>
that’s why i cant write only “/answer” or:

if update.Message.IsCommand() {

switch update.Message.Command() {

case “answer”: //that case doing well without photo. but with – program can’t see that case

handleAnswerCommand(…)
}
}

if (update.Message.Photo.IsCommand() == “answer” && update.Message.Chat.ID == supportChatID){
handleAnswerCommand(bot, supportChatID, update.Message, update.Message.Photo[len(update.Message.Photo)-1].FileID, update.Message.Caption)
}
