Azure provisioner Unified Groups - support additional extended properties

To improve the usability and customizability of groups once they are in Azure AD, it would be great if we could assign additional parameters currently not supported by the connector. Namely these parameters in the Request Body:

allowExternalSenders (boolean) allows control of whether people outside the group can email to the group (default behavior is false)

autoSubscribeNewMembers (boolean) allows members of the group to be automatically subscribed to get emails (default behavior is false)

Interestingly, it appears this can only be called by a subsequent UpdateGroup call: [Update group - Microsoft Graph v1.0 | Microsoft Docs|https://docs.microsoft.com/en-us/graph/api/group-update?view=graph-rest-1.0&tabs=http] Not sure this will work in a CreateGroup call.
