az cli cacerts.pem appending

Question

Hello, I am trying to follow this article to configure the corporate proxy. It says to append the cacerts file with my root cert. It does not say how to do so. It also says to set the REQUESTS_CA_BUNDLE but does not say how to do so. I am trying to push using az cli behind a proxy and I am getting the ssl handshake error. Any help would be appreciated.
