Hi @manouallou,
Thanks for your high rate!
The free plugin never has this option, it was in the business plugin until 2019.
According to the changes in Sep 2019, Google forbidden a LocalBusiness and Organisation schema types in the Rich Snippets for all sites except a listing/directory-sites (like Yelp or FB), according to this it’s not possible used in the business plugin:

Also Google disallows using other schema types like Product, Book or Recipe for Google map reviews.
However, some other plugins have such a workaround, I mean use a Product schema type for a map reviews and, unfortunately, Google can mark the page with this markup like a spammy rating and drop from a search. We can’t take that risk and didn’t add/keep this workaround/option in the business plugin.
Thanks!
