In our email notifications, we would like to embed QR codes

We do not want the QR code to be an attachment where a user will need to perform another click to view or download

Ideally, the QR code is embedded and we can control as to where it will appear like an image i.e. <img src="CID:Content-id">

The current transact api does not allow setting the content id of attachment in order for us to control where the QR code will appear in the email
