const elemHandles = await page.$$("a[target='pdfwindow']");
console.log('count of elements: ', elemHandles.length) // 7
    
    for (const element of elemHandles) {
      console.log('element: ', element) //element:  ElementHandle {}
      let newPage = await element.click()

      console.log('new page: ', newPage) // undefined
