Issues With Graph API Powershell Module

Question

Hi,

I've been using the Graph API Powershell module to export data from our M365 Tennancy regarding student assignments using the (Get-MgEducationClassAssignmentSubmissionOutcome -EducationClassId XXX -EducationAssignmentID XXX -educationSubmissionID XXX) If I use Select-Properties * I can see there are 'Additional Properties' that contains the Grade and feedback which is what I need. However After this is expanded, everything is under either Key or Value headings and I cannot select particular items from the list such as the points and feedback.

Any Help would be appreciated
