  const cssLink = document.createElement("link");
        cssLink.rel = "stylesheet";
        cssLink.href = "https://x.com/im_livechat/external_lib.css";
        document.head.appendChild(cssLink);

        const script = document.createElement("script");
        script.src = "https://x.com/im_livechat/external_lib.js";

        script.onload = () => {
            odoo.define("web.session", function (require) {
                const Session = require("web.Session");
                const modules = odoo._modules;
                return new Session(undefined, "https://x.com", { modules: modules, use_cors: true });
            });
            odoo.define("im_livechat.livesupport", function (require) {
                const rootWidget = require("root.widget");
                const im_livechat = require("im_livechat.legacy.im_livechat.im_livechat");
                const button = new im_livechat.LivechatButton(rootWidget, "https://x.com", {
                    header_background_color: "#4E6C62",
                    button_background_color: "#4E6C62",
                    title_color: "#FFFFFF",

                    button_text: "Chat",
                    input_placeholder: false,
                    default_message: "Hello, before we continue, can I please have your email address ?",
                    channel_name: "Main Chat",
                    channel_id: 1,
                    current_partner_id: 4,
                    default_username: "Visitor",
                });
                button
                    .appendTo(document.body)
                    .then(() => {
                        window.livechat_button = button;
                        // Ensure the button is properly appended before triggering the click
                        nextTick();
                    })
                    .catch((error) => {
                        console.error("Failed to append the livechat button:", error);
                    });
            });
        };
