I use the stealth library, but how do I change the browser's default language?
The code is as follows. How should I modify it to change the browser's stealth to the language I want?

`package main

import (
"github.com/go-rod/rod"
"github.com/go-rod/rod/lib/devices"
"github.com/go-rod/rod/lib/launcher"
"github.com/go-rod/rod/lib/proto"
"github.com/go-rod/stealth"
"time"
)

var MyDevice = devices.Device{
Title: "Chrome computer",
//Capabilities: []string{"touch", "mobile"},
UserAgent: "Mozilla/5.0 (Windows NT 18.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36",
//AcceptLanguage: "zh",
Screen: devices.Screen{
DevicePixelRatio: 2,
Horizontal: devices.ScreenSize{
Width: 1280,
Height: 1024,
},
Vertical: devices.ScreenSize{
Width: 1024,
Height: 1280,
},
},
}

func main() {
//path, _ := launcher.LookPath()
//extPath, err := filepath.Abs("fixtures/chrome-extension")
//if err != nil {
// fmt.Println("出错了:", err)
//}
u := launcher.New().Set("--disable-blink-features", "AutomationControlled").Set("no-first-run").Set("disable-default-apps").
//Set("--user-agent", "Mozilla/5.0 (Windows NT 19.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36").
//Set("--lang", "zh").
//Env(append(os.Environ(), "lang=zh")...).
//Set("load-extension", extPath).
Headless(false).MustLaunch()
//Headless(false).XVFB("--server-num=5", "--server-args=-screen 0 1600x900x16").MustLaunch()

browser := rod.New().ControlURL(u).MustConnect()
//targets, err := proto.TargetGetTargets{}.Call(browser)
//if err != nil {
//	log.Fatalln(err)
//}
//for _, t := range targets.TargetInfos {
//	if t.Type != proto.TargetTargetInfoTypeBackgroundPage && t.Title != "Extension title" {
//		return
//	}
//}
// new page clear cookie，inject stealth.JS
go browser.EachEvent(func(e *proto.TargetTargetCreated) {
	if e.TargetInfo.Type != proto.TargetTargetInfoTypePage {
		return
	}
	page := browser.MustSetCookies().MustPageFromTargetID(e.TargetInfo.TargetID)
	_, err := page.EvalOnNewDocument(TestJs)
	//_, err := page.EvalOnNewDocument(stealth.JS)
	if err != nil {
		return
	}
})()

browser.DefaultDevice(MyDevice)
page := stealth.MustPage(browser)
//page2 := stealth.MustPage(browser)
//page3 := browser.MustPage(`https://bot.sannysoft.com/`)

//stealth.MustPage(page)
page.MustNavigate(`https://bot.sannysoft.com/`)
//page2.MustNavigate(`https://bot.sannysoft.com/`)
time.Sleep(time.Hour * 10)
//fmt.Println(page3)

}

AcceptLanguage string

After I used the stealth library, I used the AcceptLanguage string attribute again, but it did not take effect. The language used was also the stealth language.

could you show us your code

could you use correct markdown format?

Now my plan is to give up using stealth. I now hope to insert some commands in browser.EachEvent to bypass detection like https://bot.sannysoft.com/. Please tell me how I can detect Plugins Length through js code. (Old) 0
Plugins is of type PluginArray failed and is not 0?
