SOAP service with microstrategy

Question

I want to consume a SOAP service with microstrategy. For that I need to prepare a Xquery document to consume the web webservice.

I am tryeing to create a New Simple Xquery using the Xquery editor that microstrategy provides (XEG)

I already have been able to connect a basic service. The problem I have here is that I need to a add a UsernameToken like this one in the header to pass throught an API Gateway.
