Use Managed identity to access Azure Blob storage from an Azure VM

Below steps are configured.

1] Azure managed identity has been enabled for the vm
2] Access granted to Azure blob storage from the vm

I wanted to clarify what will be the next steps to access the blob and list down the directories.

Do we need to configure anything on the vm to use the credentials? is CLI mandatory if i just want to access directly via a python code?

Error message received :

Listing directories in container: optitex
ImdsCredential.get_token_info failed: ManagedIdentityCredential authentication unavailable.
ManagedIdentityCredential.get_token_info failed: ManagedIdentityCredential authentication unavailable.

Code I am using:

from azure.storage.blob import BlobServiceClient
from azure.core.exceptions import ResourceNotFoundError

        try:
            print('********')
            credential = ManagedIdentityCredential()
        except Exception as e:
            print(f"DefaultAzureCredential failed: {e}")
            print("Falling back to Default Credential")

            if len(blob_path_parts) > 1:
                directories.add(blob_path_parts[0])
