Answer 1

Hi @Oleh Pokladok ,

In order to call the beta API, please ensure you have installed the Microsoft.Graph.Beta package.

Please note that, as per documentation, Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version.

Hope this helps
