Hi,
i've installed the plugin and i got the first review live.
But in regards to structured data, i can see that there's missing some fields.
I'm unable to get

"aggeratedRating"
"ratingValue"
"author"
shown with structured data.

How is this implemented?

Attatched you can find a image, displaying the missing structured data
