Please could you avoid force pushes when adding additional changes to a PR under active revision, because it trashes the review history, rendering things like "view changes since last review" non-functional. Instead, you can simply add additional commits on top of the original commit, and if rebasing on main is needed for the review to make sense, use a merge commit from main.
