How could I patch a new storage class as

default

inside a Pulumi program? E.g.:

$ kubectl get sc | grep \(default\) # find the default class currently set
$ kubectl patch storageclass openebs-jiva-default -p '{"metadata": {"annotations":{"<http://storageclass.kubernetes.io/is-default-class|storageclass.kubernetes.io/is-default-class>":"false"}}}'
$ kubectl patch storageclass openebs-jiva-csi-default -p '{"metadata": {"annotations":{"<http://storageclass.kubernetes.io/is-default-class|storageclass.kubernetes.io/is-default-class>":"true"}}}'

Right now I run these commands after I run the Pulumi program... I'm installing the OpenEBS Helm Chart via Pulumi—how do I become aware of the now newly available storage class, and set that as default?
