Where does Electron pull its ssl certificates from on Linux (Ubuntu)?

We have our root certificate for a local web servers (its signed by a local CA) in Ubuntu’s system certificate store but for some reason the Zulip application (Electron based app) doesn’t appear to be utilizing the certificates in the system wide certificate store. Firefox and Chrome are pulling the system wide certs through “p11-kit-trust.so” without issue.

Does Electron automatically pull from the system wide certificates on Linux? If so, from where?
