How to get dialog inputs to automate method located remotely

I generated several inline automate methods and tested them out. I have just moved them to a URI location and updated the MIQ methods to represent this. While I can see that the methods themselves are being called, there is no input where the dialog inputs would normally be.

How can I pass the $evm.root variables to this method? Do I have to pass them through as parameters? How do I configure this?
