Attachments in the email

Hello,

At present, the email body contains list of attachment as per below screenshot. Can I attach the file into the email body which was uploaded (stored on the drive) by a user?

Regards,
Rajan

Any file known to the app and in a directory accessible to the app can be attached. The app cannot discover files, so the file’s name must be known to the app or of a format the app could guess. The directory containing the file must be in or under the app’s primary data store directory.
