(async()=>{
    const browser = await puppeteer.launch({
        headless: false
    });
    const page = await browser.newPage();
    const mouse = await page.mouse;
    await page.goto("https://www.XXX.com");
    await page.type("-sharptxtUserName", "sa", {
        delay: 250
    });
    await page.tap("-sharpbtnLoginNew");
    await page.waitFor(2000);
    const dimensions = await page.evaluate(()=>{
        return {
            left: document.getElementsByClassName("scheduling-item")[0].offsetLeft,
            top: document.getElementsByClassName("scheduling-item")[0].offsetTop
        }
    })
    await mouse.move(dimensions.left, dimensions.top); // 
})();
