How can I use the Yotpo review app for product reviews and display on the collection page?

Yotpo being a third party app, the related information is not included by default in the data sent to Algolia. You can find more information about the Product index schema here: https://www.algolia.com/doc/integration/shopify/sending-and-managing-data/schemas/?client=ruby#schema

To index the Yotpo information, you would have to add it using named tags or metafields.

Once the Yotpo information is available in Algolia, you will have to customize your front-end to display this information and this certainly requires some development work.
