这是我的系统托盘菜单，我需要更改“开始”按钮后，点击它“停止”（并更改其行动“停止”行动）

This issue曾经提到过这一点，但我找不到“menu1”的refresh()方法。
顺便说一句，我正在macOS Big Sur 11.5.1（20G80）中测试它，我的Fyne版本是v2.3.3
这是我的代码

package main

import (
    "fmt"

    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/driver/desktop"
    "fyne.io/fyne/v2/widget"
)

var menu1 *fyne.MenuItem

func main() {
    a := app.New()
    w := a.NewWindow("SysTray")

    if desk, ok := a.(desktop.App); ok {
        menu1 = fyne.NewMenuItem("start", func() {
            fmt.Println("started")

            // after started, I change the menu label to "stop" and change the Action to stop action,
            // but I don't know how to update this to the system tray menu
            menu1.Label = "stop"
            menu1.Action = func() {
                fmt.Println("stopped")
            }
            // There is no Refresh() method for MenuItem, only for menu1.ChildMenu
            // menu1.ChildMenu.Refresh()
        })

        menu2 := fyne.NewMenuItem("menu1", nil)
        menu2.ChildMenu = fyne.NewMenu("",
            fyne.NewMenuItem("submenu1", func() {
                fmt.Println("submenu1")
            }),
            fyne.NewMenuItem("submenu2", func() {
                fmt.Println("submenu2")
            }),
        )

        menu3 := fyne.NewMenuItem("show2", func() {
            fmt.Println("menu2")
        })

        m := fyne.NewMenu("MyApp", menu1, menu2, menu3)
        desk.SetSystemTrayMenu(m)
    }

    w.SetContent(widget.NewLabel("Fyne System Tray"))
    w.SetCloseIntercept(func() {
        w.Hide()
    })
    w.ShowAndRun()
}
