xpath works in browser devtools but selenium cannot find element

steps: after login to techfetch.com, and click select all checkbox and click Multiple Quick Apply button.

Then: trying to check the "Attach Covering Letter" checkbox. I could find element in browser using //*[@id="chkCL"] xpath. But javascript nodejs script is not able to find element.

// url https://www.techfetch.com/js/js_applyemail.aspx?quickapply=true

let attachCoverCheckBox = await driver.findElement(By.xpath('//*[@id="chkCL"]'))

Process exited with code 1
