How to execute a TestComplete Method from SOAPUING?

Hi all,

I have a multiple WEb Service Request in a SOAPUI project. One of the step requires a TEST COMPLETE Method execution. Hence I have added a TEST COMPLETE Step. I would need a particular method from one of the test complete file to be executed. I have no idea what needs to be added in the marked fields mentioned in the screenshot for the test complete method to get executed. Any help in this area would be greatly appreciated.
