Get URL for Guest Access

Hi, I have created an external print pdf button and would like an accessKey to be able to auto-generate it to request a PDF file for printing.

The link looks like this:?https://website-name/wp-admin/admin-ajax.php?action=generate_wpo_wcpdf&document_type=invoice&order_ids=XXXXX&_wpnonce=XXXXXXXXXX

<?php

echo "<td><a class='btn btn-primary printPdfButton' data-order-id='" . $details->id . "'></a></td>";

?>


<script>
document.querySelectorAll('.printPdfButton').forEach(function(button) {
    button.addEventListener('click', function() {
        // Get the Order ID from the data-order-id attribute
        var orderId = this.getAttribute('data-order-id');
        
        // Construct the URL with the dynamic Order ID
        
        // var accessKey = '7beccaaece';
        
// var url = 'https://localhost/test-ecom/wp-admin/admin-ajax.php?action=generate_wpo_wcpdf&document_type=packing-slip&order_ids=' + orderId + '&access_key=' + accessKey;

        
        var url = 'https://localhost/test-ecom/wp-admin/admin-ajax.php?action=generate_wpo_wcpdf&document_type=packing-slip&order_ids=' + orderId + '&access_key=7beccaaece';
        
        // Open a new window and print the PDF
        var printWindow = window.open(url);
        printWindow.print();
    });
});
</script>
