Here’s a handy snippet if you are debugging website accessibility. Logs out the element that currently has focus.
window.addEventListener('keyup', (event: KeyboardEvent) => {
if (event.key === "Tab") {
console.log('document.activeElement', document.activeElement);
}
});

copyText.removeAllRanges(),
tempTextArea.select(),
