Need the ability to set ShowInAddressList using Update-MgUser

I am updating all my scripts that use AzureAD commands to use graph commands. I have a script that sets our guest user accounts ShowInAddressList to $true using Set-AzureADUser. When reading about Update-MgUser, it indicates the following:

-ShowInAddressList

Do not use in Microsoft Graph. Manage this property through the Microsoft 365 admin center instead. Represents whether the user should be included in the Outlook global address list. See Known issue.

I would do what it suggests but the option to ‘Show in address list’ is not available on guest accounts.

How do we get that option added to Guest Users in the Admin Portal or the option resolved and working in PowerShell?
