Add vRA deployed system name as input to a vRO powershell plugin executed script

Hi,

I have vRA 7 calling various vRO workflows for post customization of my windows server guests. I now need to configure a few domain groups and GPO's. I have the powershell code to do this but need to understand how I can get vRA to call a vRO workflow which then executes the powershell code based on the vRA system name.

I basically need to provide the powershell script I execute with the powershell plugin on my PS host the vRA deployed system name.

How can I pass that hostname variable as input to the powershell script?

Cheers
