To answer it, currently, we do not have this as an option, for the visitors to be redirected to that specific review on the location when clicking on it in the widget.

However, if Google starts to share with us such URLs through their official API in the future, we will include this option as well.

What we have as an opinion now is to be redirected to the Google location where all the reviews are placed or to select the option for the reviews to be opened on Lightbox, this way once you click on a review, that specific review will be opened on Lightbox.
