MVAD -SDK-Demo notebook does not work

I have followed the documentation to run the MVAD Python Notebook and it fails with error

`ImportError: cannot import name 'DetectionRequest' from 'azure.ai.anomalydetector.models' (c:\Python311\Lib\site-packages\azure\ai\anomalydetector\models\__init__.py)`

upon inspection of the file __init__.py DetectionRequest is indeed missing.
