Google Buisnes - How to insert only one review and from one specific person?

Question

Google

There is such a blank:
https://goo.gl/LtZDqe
This blank allows you to insert data obtained from reviews on your website.
The data is received in json. Even I’m radically dumb and can’t figure out how to display only one specific review, for example, starting from the name and surname of the person who wrote the review.
Tried like this:
$.each(json.result.reviews[author_name="Sergey Kaverin"]
Didn't work (.

Answer 1

$.each(json.result.reviews, function(i,v) {

        if (v.author_name === "Имя Человека") {
           (... старый код метода ....)
        }
     });
