Digital inking in class notebook

Year 11 did a writing activity and as I am trying to minimise the amount of pupil work I touch, they uploaded it to the assignment I had created on Teams, with a page inserted from their own area of their class notebook. The two options at that stage are either to go in through the assignment in Teams or to open the page in OneNote. You can enlarge the photo, crop it, etc.. I went to the Draw tab and selected either text mode or the pen to annotate their work and add comments. I then went back to the Assignments on Teams and added general feedback plus their overall score before returning their work.
