Calling arbitrary k8s apis using the Python client

I'd like to call the openshift machine api (/apis/machine.openshift.io/v1beta1/machines). Is there a way to do this using the kubernetes Python module? I can create an api object like this:

>>> from kubernetes import client, config
>>> config.load_incluster_config()
>>> api = client.CoreV1API()

Of course, that's a core API client, which doesn't include native support for the machine api. But the object has all the endpoint and authentication information. There is a likely looking api.api_client.call_api method, but it doesn't seem to make use of the auth information embedded in the api_client object:

>>> api.api_client.call_api('/apis/machine.openshift.io/v1beta1/machines', 'GET')
[...]
kubernetes.client.rest.ApiException: (403)
Reason: Forbidden

I can explicitly pass in auth information, but then it doesn't seem to return any content:

>>> >>> api.api_client.call_api('/apis/machine.openshift.io/v1beta1/machines', 'GET', auth_settings=api.api_client.configuration.auth_settings())
(None, 200, HTTPHeaderDict({'Audit-Id': '6f6965b5-1ad7-4c5e-ab61-343e38718ff8', 'Cache-Control': 'no-cache, private', 'Content-Type': 'application/json', 'X-Kubernetes-Pf-Flowschema-Uid': '9
5848e47-b51c-46eb-aa4f-e25130d61e09', 'X-Kubernetes-Pf-Prioritylevel-Uid': '39391d77-7b32-4aa2-93c3-9915a302d361', 'Date': 'Fri, 04 Sep 2020 19:43:59 GMT', 'Transfer-Encoding': 'chunked'}))

I can of course just use requests:

>>> requests.get(f'{api.api_client.configuration.host}/apis/machine.openshift.io/v1beta1/machines', verify=False, headers=api.api_client.configuration.api_key)
<Response [200]>

That works fine, but it smells like I'm going about things the wrong way. What's the correct way to make arbitrary API requests using the Python kubernetes module?

Referring from here you could use api_client.call_api as below to call arbitrary APIs by passing a valid BearerToken which could be a service account token.

api_client.call_api('/apis/machine.openshift.io/v1beta1/machines', 'GET', auth_settings = ['BearerToken'], response_type='json', _preload_content=False)
