Read/Write AzureAD Guest Self Signup via PowerShell

Setting the Guest user self-signup property via powershell is documented to be done via the Msonline module's `Set-MsolCompanySettings` cmdlet (-AllowAdHocSubscriptions) (documentation)

Now, I don't see a way to read this setting. There's Get-MsolCompanyInformation but no value for AdHocSubscriptions.

Also, the Msonline module is marked as deprecated and we should use AzureAD(-Preview) module instead.

But there I can't find the setting. It might be me just being unable to correctly search the documentation.

So my questions are:

how can I read the setting via powershell?
what is the "new" way to set this setting when msonline module is deprecated?

It's there, but hidden:

Get-MsolCompanyInformation | select AllowAdHocSubscriptions

Or just | fl * it. And you can also set/query it via Graph: https://docs.microsoft.com/en-us/graph/api/resources/authorizationpolicy?view=graph-rest-beta

  Thank you! I wasn't aware of this concept of hidden properties. Would I have been able to figure that out via documentation?
  Also, I now see that AllowAdHocSubsciptions is set to true in the result of the cmdlet, but Azure Portal shows this as "false" in the External Identities->External Collaboration Settings

    That's not the same setting as the Guest self-service sign-up.
