Add CA Certificate to Redash

[janvss]

Hi,

We are running a self hosted Redash V10.1 instance on a Ubuntu 20.04 VM server.
We need to query JSON data from an HTTPS API (as outlined here: https://redash.io/help/data-sources/querying/json-api).
Our institution uses a local CA to create SSL certificates, so when executing the query only an SSL handshake error is returned ("certificate verify fail").
The CA certificate was already successfully installed on the Ubuntu server and connections are possible using lynx, curl or wget.
How can I add the root CA certificate to Redash? Do I need to map the CA certificate inside the docker container, and if yes how to do that?

Thanks so much for your help!
