How to see existing data in Azure storage container mount as AKS pod inline PV?

Question

Hi, I have an Azure storage account that has a container named extracted in it, and this container has some folders with data inside as in:
- extracted
- data_1
- data_2
etc.
I have mounted the container as an inline volume in an AKS pod, setup like:

kind: Pod
apiVersion: v1
metadata:
  name: my-name
spec:
  securityContext:
    runAsNonRoot: true
    runAsUser: 1000
    runAsGroup: 1000
    fsGroup: 1000
  containers:
  - image: ...
    name: my-name
    command: ["tail"]
    args:
      [
        "-f",
        "/dev/null"
      ]
    resources:
      ...
    volumeMounts:
      - name: data-1
        mountPath: "/app/data"
        readOnly: false
    env:
		...
  volumes:
    - name: data-1
      csi:
        driver: blob.csi.azure.com
        volumeAttributes:
          containerName: extracted
          secretName: test-secret
          mountOptions: "-o allow_other --file-cache-timeout-in-seconds=120"

and I have a generic secret (type=Opaque) in the same namespace as
azurestorageaccountkey: my-key
azurestorageaccountkey: my-account name

I am able to create the pod and the container is mount in the correct mountPath, but I am not able to see the folders that exist in the container (which I can see from portal.azure GUI).

Moreover I am able to CRUD a new file from the pod (f.e. touch /app/data/newfile.txt; echo "test" > /app/data/newfile.txt; rm /app/data/newfile.txt and this is also available/accessible from both pod and portal.azure GUI) but I am not able to create a new directory (e.g. mkdir /app/data/test results in: "mkdir: cannot create directory '/app/data/test': No such file or directory")

I have tried adding "-o umask=777" or "-o umask=0777" to my spec.volumes.csi.volumeAttributes.mountOptions string but to no avail.

Is it possible (and how) to be able to see existing dirs and create new dirs in my mount-as-volume storage container?
Please let me know if I should add more details.
Thanks!
