You can use the native IsGroup and IsSuperGroup methods.

PS: Does this work in groups when the bot's privacy mode is enabled?

I'm still getting a message "You are not authorized to use this bot." , when using the bot in a group.

Leave TELEGRAM_ID empty

[Pylogmon]

When receiving a group message, should you delete the prefix before sending it?
like this:

feed, err := chatGPT.SendMessage(strings.TrimPrefix(updateText,"@" + bot.Username), updateChatID)

[waltcow]

IMO, we should support both
strings.HasPrefix(update.Message.Text, "@"+bot.Username) OR strings.HasSuffix(update.Message.Text, "@"+bot.Username)

isChatBotInGroup := update.Message.Chat.Type == "group" || update.Message.Chat.Type == "supergroup"
isAtChatBot := strings.HasPrefix(update.Message.Text, "@"+bot.Username) || strings.HasSuffix(update.Message.Text, "@"+bot.Username)
isPrivateChat := update.Message.Chat.IsPrivate()

if !update.Message.IsCommand() && (isChatBotInGroup && isAtChatBot || isPrivateChat) {


}
