You don't need live chat on your website
Live chat windows that pop-up automatically and hassle you once you've spent X seconds looking at a website are annoying, much like email subscription modals. But when I've been actually looking for support and made the choice to click on the chat button, I've generally had a great experience, so long as it's connected me to a human rather than a menu of chatbot options. It's asynchronous enough that I can keep doing something else while I wait/chat, saves me from having to spell things out or repeat alphanumeric codes over the phone, and is way quicker than email.
