Describe the bug
When using Get-MgIdentityGovernanceAppConsentRequestUserConsentRequest the UserPrincipalName and Mail properties of the CreatedBy.User Property is stored in additionalProperties instead of own explicit Properties

To Reproduce
Steps to reproduce the behavior:

1. Execute Get-MgIdentityGovernanceAppConsentRequestUserConsentRequest
2. See that UserPrincipalName and Mail is in the AdditionalProperties field

Expected behavior
UserPrincipalName and Mail should be its own parameters of the identity Object

Debug Output

Module Version
2.12

Environment Data
Both Powershell 5.1 and 7.4

Additional context
I believe this issue is due to the documentation its derived from. The userConsentRequests references the identitySet which references a generic identity Class. As identity is polymorphic it only contains displayName and id.

Start with the Get-MgIdentityGovernanceAppConsentRequestUserConsentRequest cmdlet and inspect how CreatedBy.User is represented. Compare the generated identity model with the linked userConsentRequest, identitySet, and identity documentation; done means UserPrincipalName and Mail are exposed as explicit properties rather than only through AdditionalProperties.
