Find-MgGraphCommand: Many Cmdlets in Identity.Governance lack permission information

Describe the bug

I'm trying to properly identify the permissions for Cmdlets in the Identity.Governance Module but many of them lack that information.

Expected behavior

The property Permissions should contain the Graph permissions required to use these Cmdlets, i.e. Get-MgAgreementFile (this example shows both a variant with documented, and one without documented permissions).

Find-MgGraphCommand -Command Get-MgAgreementFile | Select-Object Command,URI,Permissions

Command             URI                              Permissions
-------             ---                              -----------
Get-MgAgreementFile /agreements/{agreement-id}/files {}
Get-MgAgreementFile /agreements/{agreement-id}/file  {Agreement.Read.All, Agreement.ReadWrite.All}

How to reproduce

# Load all Cmdlets in the Identity.Governance Module
$TermsOfUseCmdlets = Get-Command -Module Microsoft.Graph.Identity.Governance

# Write all Cmdlets where the length of the array "Permissions" is 0
foreach(
  $Cmdlet in $TermsOfUseCmdlets){
    Find-MgGraphCommand -Command $Cmdlet.Name | `
    Where-Object { $_.Permissions.length -eq 0 }
}

# Gives a pretty long list of Cmdlets without any documented permissions

Latest version known to work for scenario above?

2.27.0

Known Workarounds

Using the Microsoft Graph permissions reference and guessing what could fit, but this is pretty time consuming.

Debug output

The module as 988 Cmdlets, and ther are more than 100 at least where the Permissions property is empty, providing the full output is likely not helpful but it affects Get-/Invoke-/New-/Remove- and Update-Cmdlets so therefore this output isn't complete.

Other information

No response

Start by running the reported Find-MgGraphCommand reproduction against the Microsoft.Graph.Identity.Governance module and compare the empty Permissions values with the Microsoft Graph permissions reference. Trace how Find-MgGraphCommand obtains permission metadata for Get-MgAgreementFile and related cmdlets. Done means the affected Identity.Governance cmdlets report their required Graph permissions instead of empty arrays.
