i need show to copy buttons and filter combo

I need to show the copy button and also the row quantity filter

I add the code that I use to generate the table:

$('#xxxx').DataTable({
                            "language": {
                            "url": "//cdn.datatables.net/plug-ins/1.10.21/i18n/Spanish.json",
                            buttons: {
                            
                                copyTitle: 'Dato Copiado',
                                copySuccess: {
                                                _: '%d Lineas Copiadas',
                                                1: '1 Linea Copiada'
                                            }
                            }
                           
                             }, "ordering": false  ,
                            buttons: [
                                {
                                    extend: 'copyHtml5',
                                    title: 'title example' ,
                                    text: '<div class="button-copy-kronos" data-toggle="tooltip" title="Copiar"><svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" class="bi bi-files" viewBox="0 0 16 16"> <path d="M13 0H6a2 2 0 0 0-2 2 2 2 0 0 0-2 2v10a2 2 0 0 0 2 2h7a2 2 0 0 0 2-2 2 2 0 0 0 2-2V2a2 2 0 0 0-2-2zm0 13V4a2 2 0 0 0-2-2H5a1 1 0 0 1 1-1h7a1 1 0 0 1 1 1v10a1 1 0 0 1-1 1zM3 4a1 1 0 0 1 1-1h7a1 1 0 0 1 1 1v10a1 1 0 0 1-1 1H4a1 1 0 0 1-1-1V4z"/> </svg></div>',
                                }
                            ]

                            });
