The number of unread messages in the widget

Hi! Yes, the number of unread messages were shown correctly before optimization.

This is a script with some delay in which I form a script tag for the widget and my file.

window.onload = function () {
    const siteUrl = document.location.origin;

    function createScript() {
        const chatConnection = document.createElement("script");
        chatConnection.id = "ze-snippet";

        if(siteUrl === "https://masterofcode.com") {
            chatConnection.src = "https://static.zdassets.com/ekr/snippet.js?key=d34f9844-cba6-4b57-96f5-3b30aaa3d307";
        } else {
            chatConnection.src = "https://static.zdassets.com/ekr/snippet.js?key=60bb6a3f-f42a-4ee1-84bb-48b4939af38d";
        }

        document.getElementById("js-chat-screen").after(chatConnection);
    }

    function createWidgetScripts() {
        const widgetScripts = document.createElement("script");
        widgetScripts.id = "ze-snippet";
        widgetScripts.src = `${siteUrl}/wp-content/themes/moc/js/src/chatwidget/webwidget.js`;

        document.getElementById("widget-script").after(widgetScripts);
    }

    setTimeout(function(){
        createScript();
    }, 4000);

    setTimeout(function(){
        createWidgetScripts();
    }, 5000);
};

And in my file I use a function that checks when the chat is connected so that there is no error that zE is not a function.

var waitForZopim = setInterval(function () {
    if (window.$zopim === undefined || window.$zopim.livechat === undefined) {
        console.log('loading chat');
        return;
    }

    console.log('chat connected');

    zE('webWidget:on', 'chat:unreadMessages', (number) => {
        if (number > 0) {
            $(".lets-chat-button__number").text(number);
            $(".lets-chat-button__text-inner").text("New");

            checkButtonTextWidth();

        } else {
            $(".lets-chat-button__number").text('');
            $(".lets-chat-button__text-inner").text("Let’s Chat");

            checkButtonTextWidth();
        }
    })

    clearInterval(waitForZopim);
}, 100);
