Listing the SCCM per-user deployment status remotely

Question

We are building a GUI to allow a technician to connect remotely and get the installation status of the per-user SCCM app deployment (similar as SCCM Client center).

Getting the per-machine deployment with the WMI (\DeviceName\ROOT\ccm\ClientSDK:CCM_Application) is working great.

For a "required" per-user deployment, the only thing I'm able to see is the policy under \DeviceName\ROOT\ccm\Policy\AD_USER_SID\ActualConfig:CCM_ApplicationCIAssignment but I cannot find the InstallState. The SCClient_Username.log is showing the WMI location but it doesn't exist on the device :

Got instance from WMI for \DeviceName\root\ccm\ClientSDK:CCM_Application.Id="ScopeId_0370A181-0BB6-4F5D-BE05-5128759BC63A/Application_1b584e64-a5e8-4a76-93d2-2b159a27e1d4",IsMachineTarget=false,Revision="10" (Microsoft.SoftwareCenter.Client.Data.WmiConnectionManager at GetInstance) SCClient 2022-11-18 12:24:05 5 (0x0005)

According to this https://learn.microsoft.com/en-us/mem/configmgr/apps/understand/user-deployment-technical-reference, "required" per-user deployment is using the same method as per-machine. "Available" per-user deployment received the status in realtime from the server once the user open the Software Center. This what I want to achieve remotely for a logged on user.

I tried to trigger the webmethod but there's not much documentation / example on how to use it :
$Url = "http://SCCMServer/CMUserService_WindowsAuth/applicationviewservice.asmx"
$Services = New-WebServiceProxy $Url -UseDefaultCredential

How do I call the GetFilteredApplications method ?

If the intent is to capture status of the deployment by service desk, then maybe utilizing rbac and giving read only access to the console\reports will be a better option.
