Weekly assignment (Kami&Canvas)

Has anyone tried to use Kami to create a “notes” page for students?

Ideally, i want to make a pdf capture sheet for students to use all week in my class. I’d like to be able to assign and submit it via canvas (our LMS) and have students receive it on Monday , edit and add to it every day, and then submit it on Friday.

I"ve tried just creating a pdf in google drive and adding it to an assignment via the external tool “Kami /google drive”, but students report that they don’t see their annotations from the previous day. I’m not sure how they should be re-opening the file after the inital day.

Does anyone have a clear step-by-step way to do this???
