update.EditedMessage is not work in b.RegisterHandlerMatchFunc

package main

import (
"context"
"fmt"
"github.com/go-telegram/bot"
"github.com/go-telegram/bot/models"
"log"
"os"
"os/signal"
)

// Send any text message to the bot after the bot has been started

func main() {
ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt)
defer cancel()

opts := []bot.Option{
	bot.WithDefaultHandler(defaultHandler),
}

b, err := bot.New("6xxxx", opts...)
if nil != err {
	// panics for the sake of simplicity.
	// you should handle this error properly in your code.
	panic(err)
}

b.RegisterHandlerMatchFunc(matchFunc, helloHandler)
b.RegisterHandlerMatchFunc(matchFunc2, helloHandler2)

b.Start(ctx)

}

func matchFunc(update *models.Update) bool {
if update.Message == nil {
return false
}
//time.Sleep(5 * time.Second)
fmt.Println("✅✅✅hello matchFunc1")
return update.Message.Text == "hello"
}

func matchFunc2(update *models.Update) bool {
fmt.Println("❇️❇️❇️❇️:matchFunc2", update.EditedMessage)
if update.EditedMessage == nil {
return false
}
//time.Sleep(5 * time.Second)
fmt.Println("❇️❇❇️❇hello matchFunc2")
return true
}

func helloHandler(ctx context.Context, b *bot.Bot, update *models.Update) {
//time.Sleep(1 * time.Second)
log.Println("🔥hello handler:" + update.Message.Text)
}
func helloHandler2(ctx context.Context, b *bot.Bot, update *models.Update) {
//time.Sleep(1 * time.Second)
log.Println("🔥🔥hello update.EditedMessage:", update.EditedMessage)
}
func defaultHandler(ctx context.Context, b *bot.Bot, update *models.Update) {
log.Println("🌹 default handler", update.EditedMessage)
}

/////////// it dont work

When I use this to edit a message that has already been sent, the helloHandler2 never triggers. Moving the code to defaultHandler can correctly print out the message, proving that it works. But why doesn't helloHandler2 work?

update.EditedMessage sent by Telegram server. While telegram server sent a message, exactly one field will be defined. update.Message / update.EditedMessage, but not both.

You edit original update.Message, but check update.EditedMessage in matchFunc2

but why it can work in func defaultHandler(ctx context.Context, b *bot.Bot, update *models.Update) {
log.Println("🌹 default handler", update.EditedMessage)
}

[pd5200]

b.RegisterHandlerMatchFunc(handle.MatchfilterFunc(handle.IsPrivate, handle.IsCallbackQuery, handle.IsAuthAdmin), handle.CallbackQueryHandle(rCallback)) //no work
b.RegisterHandlerMatchFunc(handle.MatchfilterFunc(handle.IsPrivate, handle.IsReply, handle.IsAuthAdmin), handle.ReplyHandle(rReply))      //work
b.RegisterHandlerMatchFunc(handle.MatchfilterFunc(handle.IsPrivate, handle.IsNotReply, handle.IsAuthAdmin), handle.NotReplyHandle(rText)) //work
I do it like this.

If not using pointers, is it possible? Like this? It will work?
var updates tgbotapi.UpdatesChannel = bot.GetUpdatesChan(u)
