Our company is using a ZScaler proxy that replaces SSL Certs with a company self-signed root CA. My Ubuntu system has this certificate trusted in its trust store, so I can (at the ubuntu level) connect to ssl like https://get.fiddler.com etc. I can also login to my account via Browser.

But if I run the AppImage installer file via CLI on Ubuntu the login fails and the console shows an issue with the SSL cert:

This is expected, as explained above, there is a root cert that I need to tell the electron/node runtime to trust.

How do I pass a trusted certificate to the installer?
