add a PDF Document to Outlook via send button in javascript

Hello, dear community,

I have a question. As you may know, the MS Edge browser can run a new viewer called the Acrobat Reader Engine. I programmed an interactive document in JavaScript, and it works well when I use Acrobat Reader. The main function is built around adding the PDF-File to Outlook. When I open the document with the new Acrobat Reader Engine, that function doesn't work, maybe because I use the mailDoc() function?

Best Regards

Andi
