How can I insert dynamic product review schema without an app?

[divinesacred1]

Hey there,

I have product schema implemented for all of my products. One of these fields is the review portion, called "aggregateRating."

The app we use for product reviews, Air Product Reviews, currently automatically generates dynamic product review schema for all products, and uses the "aggregateRating" field to do so.

However, I'd like to know if it's possible to insert dynamic review schema without the use of the app.

I found the product-schema.liquid snippet in the shopify code. However, is it possible to insert dynamic review schema here? I have tried testing various fields to no avail. See below please.

The first image shows the current product schema. The second shows the available "product" dynamic fields.

Is it possibly to insert the "aggregateRating" field using this method? Perhaps I need to use another field.
