3cx change bubble button style in Wordpress functions.php - move up an async button and styling it after waiting fetch for async dom created

I have been struggling with the moving up of the chat bubble overriding my theme bottom login/out web app bar for 2 days:

Tryed to:

1. modify in Wordpress the child style.css and the functions.php

The style of the theme was not applying in style.css modified the <button id="wplc-chat-button"

`/*

#wplc-chat-button {bottom: 100px!important}
`

2. using jquery to add css to the chat bubble after manually applying the bottom:70px!important to Chrome

3. using jquery to add css to the chat bubble parent div

4. using jquery to add css to the chat bubble grandparent div

    function add_custom_js() {
    ?>
    <script type="text/javascript">

        function querySelectorAllShadows(selector, el = document.body) {
          // recurse on childShadows
          
             /**
             * Finds all elements in the entire page matching `selector`, even if they are in shadowRoots.
             * Just like `querySelectorAll`, but automatically expand on all child `shadowRoot` elements.
             * @see https://stackoverflow.com/a/71692555/2228771
             */
          const childShadows = Array.from(el.querySelectorAll('*')).
            map(el => el.shadowRoot).filter(Boolean);

          // console.log('[querySelectorAllShadows]', selector, el, `(${childShadows.length} shadowRoots)`);

          const childResults = childShadows.map(child => querySelectorAllShadows(selector, child));
          
          // fuse all results into singular, flat array
          const result = Array.from(el.querySelectorAll(selector));
          return result.concat(childResults).flat();
        }

        jQuery(document).ready(function(){
            setTimeout(function() {
            // sposta la bubble chat
                
            // Sposta il div #callus-container
                var allMatches = querySelectorAllShadows('#wp-live-chat-by-3CX');
                if(allMatches && allMatches.length > 0){
                    var callusContainer = jQuery(allMatches[0]); // Prendi il primo match
                    if(window.innerWidth <= 430) {
                        callusContainer.css({'position':'fixed','bottom':'105px','right':'5px'});
                    }
                }
                
            }, 3000);  // 3 secondi di ritardo
        });
    </script>
    <?php
}
    add_action('wp_head', 'add_custom_js', 100);
