Query for discount won't show what customer segment is applied

I have a discount code being applied to a specific customer segment, but when I query it using the GraphQL API, the customerSelection is always returned with customerSelection.__typename: "DiscountCustomers" which is intended for when I select specific customers for the discount.

If the Discount is set to a specific segment, shouldn’t I be able to query for that segment?

In a fun twist, the GraphiQL app suggests says customerSelection of DiscountCustomerSavedSearches { savedSearches } is deprecated in favor of DiscountCustomerSegments.segments. But that property (though it sounds like just what I need) doesn’t show up in the schema and won’t come back in a query.

Is there a plan to make this work in the near future?

Thanks,

Brendan
