document.getElementsByClassName returns a https://developer.mozilla.org/en-US/docs/Web/API/HTMLCollection which is an array like object. You cannot call click directly on the collection, you must select an element from with the collection.

document.getElementsByClassName('btn_addtocart')[0].click();

Personally I prefer to use query selector for fetching a single html element.

document.querySelector('.btn_addtocart').click();

Anything you are having problems with JavaScript I'd suggest running your script directly in DevTools. See https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting#javascript-debugging
