How to use (client) mTLS in the http-request node?

I have a server endpoint secured with an mTLS based authentication which I want to use for a GET request in the http-request node. I expected this to simply work by setting SSL/TLS configuration node with the crt, key and ca files but apparently it doesn't and instead throws "UNABLE_TO_GET_ISSUER_CERT_LOCALLY"

I've already tried what I found online adding the ca.pem path as NODE_EXTRA_CA_CERTS with no success so far. Is this supposed to work and I don't get it or might there be a problem? Or is it simply not supported?

EDIT: Ok, nvm. It works when removing "Verify server certificate" so maybe there is something wrong with the client cert and ca cert files common names. Have to look into that
