Annotations Complete - Now what? Google Classroom

In my school, we are using Chromebooks, not iPads. I am using Google Classroom for my math students to submit work. The most popular way is for them to complete their work on paper, take a picture on their phone, and submit it via Google Classroom. I was able to open with Kami (after the conversion process) and make corrections and give feedback. Then what? Is there a way for Kami to easily save the edited version of their work right on the Google Classroom page? Right now it looks like my only choice is to save it to my Google Drive and then share it with the student. That defeats the purpose of using Google Classroom, where all documents are “housed” within the stream between the students and me.

The link provided doesn’t work. I have a similar issue where students can see my annotations on PDFs but not if they submitted jpeg or png files. How do they see the annotations once the assignment is returned on google classroom?
