For example, in a Student Assignment Submission form, there are fields such as Image and Files that allow users to upload images or documents.
When configuring the Email Notification for this form, there is an option in the message editor called Insert fields, which allows form fields to be inserted into the email content. However, in this list, the Image and File Upload fields do not appear as selectable options, even though they are part of the form and contain submitted data.
Ideally, when Include user submitted data is selected, all submitted data including uploaded files or images should also be included or attached in the email, as they are part of the form submission.
