How to get access to elements in JS code in livewire 3 ?

In livewire 2 I used method window.livewire.find when I needed to get access to elements in JS code, like :

<script>
    // import { setAppTitle } from 'app';

    function adminAppImageComponent() {
        return {
            getSubmitLabel: function () {
                const doc = document.getElementById("app_image_admin_page_container"); // ref to container  div
                console.log('doc::')
                console.log(doc)

                var wireIds = window.livewire.find(doc.getAttribute("wire:id"))
                console.log('wireIds::')
                console.log(wireIds)

                if (wireIds.get('updateMode') == 'edit') {
                    return "Update"
                }
                if (wireIds.get('updateMode') == 'add') {
                    return "Add"
                }

            },

It worked for me and I had dynamic text of label.

But in livewire 2 I got error on the same code :

Readiing docs at https://livewire.laravel.com/docs/upgrading I did not find any hints how can I do it ?

            "laravel/framework": "^10.43.0",
            "livewire/livewire": "^3.4"

Thanks in advance!
