Researchers at the University of Michigan would like to perform AI analysis of the comments left by reviewers in Canvas' Peer Review feature. After browsing through the Canvas API documentation and exploring the Canvas live API, I've not been able to find an API function that will let us access those comments.

Does an API function exist for reading peer review comments?

I've found that the API will show me who has been assigned to review each author's submissions, but I can't find the review comments. The only comments I've been able to access are the submission comments, but those are made by the instructor/TA only, they don't include peer review comments.
