display the customer’s country ?

I operate a global online store, so my customers are from many different countries.
Is it possible to display the customer’s country alongside their review?

Also, can we add a tab in the My Account section where customers can view and manage their own reviews? Would it be possible for them to edit their reviews directly on the site?

The Review Authors addon allows people to edit and delete their own reviews from the frontend.

Make use of the Assigned User option and assign new reviews to the current user. That way, it’s easy to filter reviews by assigned user and only display reviews on the customer account page that have been assigned to them.

Site Review does not provide a way to add a “tab” on your page, it’s not a layout plugin but a reviews plugin. It only concerns itself with ratings and reviews. How you choose to display the reviews on your page is up to you.

Is there a shortcode that displays a list of a customer’s own reviews, with the option to edit them directly on the site?

See my answer above.
