Oracle APEX create PDF and send mail attachment

I am having trouble creating a PDF at the same time and then sending the same file via e-mail. I tried to use apex_util.get_print_document but I don't know what to enter in p_report_query_name and p_report_layout parameters. I also tried to use html2pdf but I don't know how to send the created pdf to the e-mail attachment. Please help

js:
function pdf_DLoad (p_id) {
var element = document.getElementById(p_id);

var opt = {
margin:       1,
filename:     'myfile.pdf',
image:        { type: 'jpeg', quality: 0.98 },
html2canvas:  { scale: 2 },
jsPDF:        { unit: 'in', format: 'letter', orientation: 'portrait' 
}
};
html2pdf().set(opt).from(element).outputPdf('datauristring')
.then(function (res) 
{
this.blobString = res;
console.log(res);

apex.item("P10_NEW").setValue(res);


});
