Automate Storage vMotion - MiqVimVm.rb

I’m needing to create an automate method to perform a storage vmotion. @rpo was nice enough to point me to the MiqVimVm.rb in lib/VMwareWebService.

However, I’m unclear how to execute the code. How would I insert RelocateVM_Task from MiqVimVm.rb into a method in Automate?

Checking to see if anyone might have an answer on how to execute this? Thanks!
