i don't how to send message to this group

I am using this code

sender := message.NewSender(tg.NewClient(client))
fmt.Println("groupId", groupID, reflect.TypeOf(groupID))
peer := &tg.InputPeerChat{
	ChatID: groupID, // Replace with the ID of the group you want to send the message to
}
uc, err := sender.To(peer).Text(context.Background(), "hi")
if err != nil {
	panic(err)
}
