Is there a way to have AppConfigurationClient JavaScript library configured to validate against a self signed certificate correctly?

Our company works behind a VPN where there's a SSL certificate used. However, when working with the AppConfigurationClient behind this firewall, I get the following error:

An error occurred: FetchError: request to https://xxxxxx.azconfig.io/kv/AppConfigurationKeySample?api-version=1.0 failed, reason: self signed certificate in certificate chain

I do have a copy of a trusted certificate locally, but not sure how I can easily configure this to accept it.
