FortiClient VPN / SSL AddOn - Scripting Properties

Hi

I'm working on a script to import all equipment. I would like to set FortiSSL VPN Properties on the site group. When i copy it i can see that it's all set as an XML under properties. I have looked at the forums i can see that for Bomgar for example there is an object where it is possible to set the properties:
New-Object RemoteDesktopManager.AddOn.BomgarConsoleAddOn.BomgarConsoleConfiguration;

Is there something like that for FortiSSL?
