vRA 7.2 workflow template help

So I'm  used to 6.2 that came with a workflow template.  Everything was predefined on what I need to have.

Then I just created new variables that extracted my values from vCACVmProperties.

ex: var user = vCACVmProperties.get('__Legacy.Workflow.User');

From what I've ready, I should just be able to create a payload property that would bring in all the properties like before....but how do i extract those?

something like this?  var user = payload.get('__Legacy.Workflow.User'); ?

I wish they created a similar workflow template for 7.2, like they did with 6.2, especially with the new changes.
