Magento2.4.6: setTimeout() doesn’t work on server on checkout page but its working on local checkout page, whats the reason?

Here is the code

<script>
    require([
        "jquery"
    ], function($) {
        'use strict';
        $(document).ready(function () {
            setTimeout(
                function(){
                    let telephone = $('input[name="telephone"]');
                    telephone.keypress(function() {
                        console.log("Formatting phone number with keypress");
                        telephone.attr('maxLength', '13');
                        telephone.attr('minLength', '13');
                        telephone.addClass('validate-phone-13');
                        telephone.attr('type','tel');

                        let x = $(this).val();
                        x = x.replace(/D+/g, '').replace(/(d{3})(d{3})(d{4})/, '($1)$2-$3');
                        $(this).val(x);
                    });
                    telephone.focusout(function(){
                        console.log("Formatting phone number with focusout");
                        let x = $(this).val();
                        x = x.replace(/D+/g, '').replace(/(d{3})(d{3})(d{4})/, '($1)$2-$3');
                        $(this).val(x);
                    });
                }, 8000);
        });
    });
</script>

This script loads in DOM and I can see the code when inspecting. but it doesn’t execute code. it works fine on the local machine.
Does it have to do something with timeout time?
