Using PowerShell to get user PIN from FIM CM?

Does anyone have a clue how to retrieve user PIN from FIMCM via the Powershell?

I looked couple of links:

https://msdn.microsoft.com/en-us/library/microsoft.clm.provision.executeoperations.getuserpin%28v=vs.100%29.aspx

Which leaded me to a conclusion that this would be a doable thing, however, I'm not that skilled at .NET assemblies and Powershell to get this working so I was hoping that someone has a working solution already made or could at least give a example code how to get it working..
