App Store Connect API - How to get current app rating?

Hi,

I've been able to use the App Store Connect API to get the list of all customer reviews and I know that it contains the number of total reviews, but it doesn't include the current rating out of 5 stars.

How can I get this number without paging through every single customer review?

Yeah, I'm looking forward to an API endpoint that returns the app ratings (1 to 5 stars) with territory, app version and create date fields at least. Currently only reviews endpoint is available and it's partially useful because it doesn't picture the whole app performance.
