We can use querySelectorAll  and querySelector to get any element from DOM. querySelector  helps to get first element from dom and querySelectorAll  helps to get all elements as an array from DOM.

// get array of all elemnts having tag aria-label with text 'First name'
var singleElement = document.querySelector('[aria-label="'First name"]');


// get array of all elemnts having tag aria-label with text 'First name'
var elementsArray = document.querySelectorAll('[aria-label="First name"]');
