Add starts rating in woocommerce product comment from backend

I collect reviews from different websites and I would like to be able to add them manually to my products in woocommerce, how can I add the star rating from the back office over the text? in the comment there is no metabox of the choice. I searched for this information and the only document found is this woocommerce report in the issue sections: https://github.com/woocommerce/woocommerce/issues/25656

can you help me understand how to add the rating change from the backoffice on new comments?

Thanks
