Go to one of the review back end pages and scroll down, it is under Affiliate fields, then review additional info. You need to add them in under the Affiliate info list options. You can add anything here name wise
I have tried to use that one but it does not look very good on the page and also there must be a conflict as it doesn’t not allow you to add in any URLs
I have tried a schema FAQ plugin but it does not show correctly on a review page. Also tried yoast but that need gutenberg/block editor which is not available on the review pages.
