我正在嘗試使用 playwright 測試在選項卡之間切換，但它沒有控制 windows 元素。劇作家里面有沒有類似selenium driver.switchto().window()的方法？const { chromium } = require('playwright');(async () => {    const browser = await chromium.launch({ headless: false, args: ['--start-maximized'] });    const context = await browser.newContext({ viewport: null });    context.on("page", async newPage => {        console.log("***newPage***", await newPage.title())    })    const page = await context.newPage()    const navigationPromise = page.waitForNavigation()    // dummy url    await page.goto('https://www.myapp.com/')    await navigationPromise    // User login    await page.waitForSelector('#username-in')    await page.fill('#username-in', 'username')    await page.fill('#password-in', 'password')    await page.click('//button[contains(text(),"Sign In")]')    await navigationPromise    // User lands in application home page and clicks on link in dashboard     // link will open another application in new tab     await page.click('(//span[text()="launch-app-from-dashboard"])[2]')    await navigationPromise    await page.context()    // Waiting for element to appear in new tab and click on ok button    await page.waitForTimeout(6000)    await page.waitForSelector('//bdi[text()="OK"]')    await page.click('//bdi[text()="OK"]')})()
