If changes have been made after a reviewer has submitted their initial review, the review owner can request them to re-review.
To do so, follow these steps:
Open the Review panel from the right-side menu and access the Details tab.
Locate the reviewer's name in the list of reviewers. As they have submitted their review, they will have a green tick icon beside their name.
Click the Re-request review button beside their name.
This action will notify the reviewer that a new review is required, and they will have the 'submit review' option available to them again.
