Limitation of mailto: link QR codes.

Some QR code scanners such as Google Lens will not pick up the BCC and CC field in a mailto URL. They will ignore those fields and only read the To, Subject and Body of the mailto code

Which means If we make a QR code of this mailto link

The scanner will only detect anything other than CC and BCC as shown below

This limitation can be bypassed by using services which offer dynamic redirecting to mailto URLs through their backend server.
