Product snippets structured data issues

Hello.
How can we find a solution to the “Product snippets structured data problems detected” problem from Google?
Identified issues:
Missing field “aggregateRating”
“review” field is missing

Hello,

Could you please check how it works with some default WordPress themes like TwentyTwenty or WooCommerce Storefront to understand is it our theme issue or not?

Regards
