How do I configure the network proxy?

Hi everyone, At work I use Ubuntu and my internet access has to go through a Squid proxy with authentication. Ex: http:/ /user:pass@ip:port

This detail is usually the root cause of problems with my applications that don’t respect the http_proxy variables and others.

And this is probably what’s preventing me from using the agents in the IDE (see image).

So, how do I inform AntiGravity about my proxy configuration?
