How to use the API through a Proxy?

This may sound like a stupid question but I can't make it work behind a proxy.
What is the procedure to configure proxy information? Should it be done through NodeJS?
_(I tried to configure axios default to setup the proxy but it does not seem to work)_

Thanks,

The issue mentions NodeJS and axios but names no repository file, entry point, or test. Start by locating the API client configuration and any existing proxy documentation, then determine the supported configuration path. Done should clearly document how proxy information is configured and include a reproducible verification path.
