How to fetch the 'benefits' of an in-app product or subscription with Google Play Billing Library?

I'm using the Google Play Billing Library version 3 to fetch available in-app products and subscriptions.

After calling querySkuDetailsAsync on the BillingClient object, I'm correctly getting the SkuDetails for each product.

In the Google Play Console, I typed-in some benefits into the "Benefits" field, however, I don't see any methods for getting them.

I'm able to get the name, price, description of the product, but not the benefits.

How can I fetch the benefits of an in-app product or subscription?
