Possibility to retrive includes?

Hey, not sure if it's missing or I don't know how to exactly use it. However, I can't retrieve 'included' from any out of the box options eg. list, get, get_first. However, if I get retrieved payload from underlying methods then it's there. So I assume, parameter is passed while calling API, however, method returning payload only process 'resources' and 'included' is omitted.

Using CF CLI:

cf curl /v3/apps/9a81aaf5-7dac-4adc-a764-263b98935707?include=org | jq -r .included.organizations[].guid
42b716bb-42c5-4bcf-9c1c-f4be4d11685b

Using Python client:

app = client.v3.apps.get("9a81aaf5-7dac-4adc-a764-263b98935707", include="org")
print(json.dumps(app["included"], indent=4))
    print(json.dumps(app["included"], indent=4))
KeyError: 'included'

By changing the first line only, a single request fetches all the data. The navigation from app to space and space to organization remains unchanged.
app = client.v3.apps.get("app-guid", include="space.organization")

The managers provide the same methods as the V2 managers with the following differences:
get(**kwargs): supports keyword arguments that are passed on to the API, e.g. "include"

Reproduce the example with v3.apps.get(..., include="org") and compare its result with the payload returned by the underlying request. Trace how the apps manager processes API responses, then verify that the included data remains available and that the existing navigation behavior still works for include="space.organization".
