Invoke-WMIMethod convert to Invoke-CimMethod with ciminstance as Argument error

So, trying to trigger a software update in SCCM with Invoke-CimMethod instead of Invoke-WMIMethod.

WMIMethod Works:

$UpdateID = 'Site_1EED8E47-D4D8-4823-883C-4FFE753FA233/SUM_0af47e05-17cb-4756-8610-09ce486df1ba'
$FeatureUpdate = Get-WmiObject -Namespace Root\CCM\ClientSDK -Class CCM_SoftwareUpdate -Filter "UpdateID like '$UpdateID'"
Invoke-WmiMethod -Namespace Root\ccm\clientSDK -Class CCM_SoftwareUpdatesManager -Name InstallUpdates -ArgumentList $FeatureUpdate

Note that $FeatureUpdate is a instance of an update:

$FeatureUpdate.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     ManagementObject                         System.Management.ManagementBaseObject

Now with Invoke-CimMethod:

$Instance=Get-CimInstance -Namespace Root\CCM\ClientSDK -Class CCM_SoftwareUpdate -Filter "UpdateID like '$UpdateID'"
Invoke-CimMethod -Namespace Root\ccm\clientSDK -Class CCM_SoftwareUpdatesManager -MethodeName InstallUpdates -Arguments @{CCMUpdates = $Instance}

Invoke-CimMethod : Type mismatch for parameter "CCMUpdates"

Note the Instance:

$instance.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     CimInstance                              System.Object

Am I missing something on triggering the install with the arguments? Not sure if this helps..

 -like 'InstallUpdates'}).parameters

Figured it out after letting it sit for the day. Found some posts to lead me in the right direction.

Final final:

$UpdateID = 'Site_1EED8E47-D4D8-4823-883C-4FFE753FA233/SUM_0af47e05-17cb-4756-8610-09ce486df1ba'
$Instance = @(Get-CimInstance -Namespace ROOT\ccm\ClientSDK -ClassName CCM_SoftwareUpdate -Filter "UpdateID like '$UpdateID'")
Invoke-CimMethod -Namespace ROOT\ccm\ClientSDK -ClassName CCM_SoftwareUpdatesManager -MethodName InstallUpdates -Arguments @{CCMUpdates = [ciminstance[]]$Instance}

Returns, and updates install:
