Export Graph openTypeExtension via Powershell

Hello. I'm trying to view and export openTypeExtensions in Powershell. I can see them in Graph by user(see screenshot), but am not having luck figuring out how to see them in Powershell.

I found this query example, but they are different extensions.

Get-AzureADUser -ObjectId 'username' | select -ExpandProperty ExtensionProperty

I can't seem to find the correct language to query the openTypeExtensions.

Thank you.
