invoking CimInstance method for store apps

Hey @KnifMelti
I found your comment in

Line 16 in 9f00859

# Can't get it done with Get-CimInstance, using deprecated Get-WmiObject

In short it is doable:
below the comparison of both syntaxes

• wmi

	$namespaceName = "root\cimv2\mdm\dmmap"
	$className = "MDM_EnterpriseModernAppManagement_AppManagement01"
	$wmiObj = Get-WmiObject -Namespace $namespaceName -Class $className
	Write-ToLog $action_string "green"
	$wmiObj.UpdateScanMethod() | Out-Null

• cim

	$namespaceName = "root\cimv2\mdm\dmmap"
	$className = "MDM_EnterpriseModernAppManagement_AppManagement01"
	$methodName = 'UpdateScanMethod';
	$cimObj = Get-CimInstance -Namespace $namespaceName -ClassName $className -Shallow;
	# you can get the returncode like that
	$result = $cimObj | Invoke-CimMethod -MethodName $methodName;
	$result.ReturnValue

In long:

Oct 20, 2023 in #438 I tried to convert it to CIM, but failed and besides the original WMI works (it's just a deprecated way of doing things according to MS).

I'm using Pieces for Developers for my snippets collection and sources so I can remember ;)

The $result is a table and I couldn't figure out how to extract just the ReturnValue therefore I skipped it:

__GENUS          : 1
__CLASS          : __PARAMETERS
__SUPERCLASS     : 
__DYNASTY        : __PARAMETERS
__RELPATH        : __PARAMETERS
__PROPERTY_COUNT : 1
__DERIVATION     : {}
__SERVER         : HARDMELTI
__NAMESPACE      : ROOT\cimv2\mdm\dmmap
__PATH           : \\HARDMELTI\ROOT\cimv2\mdm\dmmap:__PARAMETERS
ReturnValue      : 0
PSComputerName   : HARDMELTI

Your solution works perfectly! 👌

Done and done..
I'm glad I could help, I still have about 150 outstanding notifications from GH to catch up on changes in WAU.
