SOAP Request and Proxy in UiPath Studio

Hi everybody !

I would like to use a SOAP Request Activity with the given url " http://www.webservicex.com/globalweather.asmx?wsdl " but I get the error “There was an error downloading…” (see screenshot attached)
I guess it is due to the proxy parameters not provided (mandatory in the company network I use).

Does anybody know how to configure Proxy parameters for SOAP Request or in UiPath Studio more globaly ?

Thanks a lot for your help !
