I'm stuck with a problem where I need to attach a PDF to an email. The email functionality should work just like mailto, when the user clicks on the button it should open the mailbox with the attachment added. What I have with me is the attachment URL.

I tried using SMTP.js, and the attachment is working fine, but it is not opening the mailbox where the user can enter/edit from/to/cc/subject etc, but straightaway sending the email to the hardcoded address.

Is there any solution in js for this requirement or any services I could make use of?

Thanks in advance.
