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"

Riproduci l’esempio con v3.apps.get(..., include="org") e confronta il relativo risultato con il payload restituito dalla richiesta sottostante. Traccia il modo in cui apps manager elabora le risposte dell’API, quindi verifica che i dati inclusi rimangano disponibili e che il comportamento di navigazione esistente continui a funzionare per include="space.organization".
