Thanks to #154, the https-proxy-agent now emits a proxyConnect.
The same has been wished for the http-proxy-agent as stated by @TooTallNate in the PR but was not possible until DefinitelyTyped/DefinitelyTyped#65408 has been merged (which is now).
It would be great to also have this for this agent as well.
Thanks for your valuable work! 🙏
