How to add proxy host and port to the web Api integration in latest version of Appian

Hi All,

As we checked in the particular KB article, there is an option called proxy host, port while configuring the webservices. Refer below article.

KB-1306 How to integrate with web services requiring an HTTP proxy server - Appian Knowledge Base - Support - Appian Community

However, in the latest version of Appian, while implementing with web Api integration, we do not have the option for passing the proxy host and proxy port.

What is the best process to implement the HTTP proxy in web Api?
