Import reviews from the standard "Comments" section of WP

Hi

My website is: https://www.parfumio.ro

WP has a standard “Comments” section/feature, in my case https://www.parfumio.ro/wp-admin/edit-comments.php

I have a page on my website called “Testimoniale” (https://www.parfumio.ro/testimoniale/) which until now received ratings/testimonials from my clients via that standard Comments section of WP.
I want to transfer/import all those already receved testimonials to my newly installed WP Customer Reviews plugin.

What should I do?

Thanks a lot,
Larry
