Getting response from Blue Prism integration

Hello,

We need to get message from Blue Prism integration after integration call is successful.  When we call integration directly in integration object we get response in raw response like this:

"<soap:Envelope xmlns:soap='schemas.xmlsoap.org/.../' xmlns:xsi='www.w3.org/.../XMLSchema-instance' xmlns:xs='www.w3.org/.../XMLSchema' xmlns:soapenc='schemas.xmlsoap.org/.../'>
<soap:Body>
<Message xsi:type='xs:string'>Successfully completed process</Message>
</soap:Body>
</soap:Envelope>"  

But, when we call integration using call integration smart service in process model and try to save response we get empty result: [] saved in process variable. 

Is there a way to get the raw http body while calling the integration smart service so I can parse it manually?
