   Heres a workaround to make Entra/AAD token work like 
`DefaultAzureCredential` inside Fabric notebook env
   
   ```
   from azure.core.credentials import AccessToken, TokenCredential
   from datetime import datetime, timedelta
   
   class UserTokenCredential(TokenCredential):
       def __init__(self, token: str, expires_on: datetime = None):
           self._token = token
           self._expires_on = expires_on or (datetime.utcnow() + 
timedelta(hours=1))
   
       def get_token(self, *scopes, **kwargs):
           return AccessToken(self._token, int(self._expires_on.timestamp()))
   
   token = notebookutils.credentials.getToken('storage')
   token_credential = UserTokenCredential(token)
   
   # Example: passing to a BlobServiceClient
   from azure.storage.blob import BlobServiceClient
   client = 
BlobServiceClient(account_url="https://<account>.blob.core.windows.net", 
credential=token_credential)
   ```
