Setup

Select a Category and Purpose in Site administration -> Users -> Privacy and Policies -> Data registry

Create a course with an assignment and an enrolled student "s1".

Ensure "Online text" is enabled for submissions and "Annotate PDF" and "Feedback text" is enables for feedback types.

Grade that student in the assignment and include a file (image) in the feedback comments.

As that student, create a privacy request to export all my personal data.

As an admin approve this privacy request.
