Product Reviews APP - get Author Name

Hi ALL,
I’m trying to add structured data to my product pages.

https://search.google.com/test/rich-results/result/r%2Fproduct?id=xPfBy1kUSs7DjJMVTX3O1A

However I’m missing the review fields.

I’m using this APP for the reviews and I need to extract the information about the Author
https://apps.shopify.com/product-reviews

I know some data from the APP is stored in:

{{ product.metafields.spr.reviews }}
{{ product.metafields.reviews.rating }}
{{ product.metafields.reviews.rating_count }}

Therefore and I’m extracting the rating value data like this:

{%- assign rating_value = product.metafields.spr.reviews | split: '"ratingValue": "' | last | split: '"' | first | plus: 0 -%}​

and rating count like this:

{%- assign reviews_count = product.metafields.reviews.rating_count -%}

But I’m missing the information for Reviews Author.

I can see in the settings there is

{{ review.author }}​

But I can’t access this variable in the templates.

Do you know how can resolve this issue and access the Author?

Kind Regards,

Did you resolve this?
