How to create a popup after customer logs in

I am new to Magento..I have successfully created a popup using modal widget in customer_account_index.xml, but this popup works only when customer clicks on My account tab. I am looking for complete code that will show a popup with customerId. Once user clicks the popup, it should redirect to a specific url. Following code is not useful to me now as I need the popup only once right after the user logs in. I have researched about customer_login event, but none of the solutions worked for me.

My phtml file looks like this

<div id="modal-content"></div>
<script>
    require(
        [
            'jquery',
            'Magento_Ui/js/modal/modal'
        ],
        function($, modal) {
            let customerId = "<?php echo $id; ?>";
            alert(customerId);
            const ajaxUrl = customurl;
            const redirectUrl = redirecturl;
            const title = sometitle;
                        let options = {
                            type: 'popup',
                            responsive: true,
                            innerScroll: true,
                            title: title,
                            buttons: [{
                                text: $.mage.__('OK'),
                                class: 'modal-close',
                                textalign: 'center',
                                click: function (){
                                    window.location.href = redirectUrl;
                                    this.closeModal();
                                }
                            }]
                        };

                        modal(options, $('#modal-content'));
                        $( window ).load(function() {
                            $("#modal-content").modal("openModal");
                        });
                    }
                }
        });````
