How do I set the TLS field in Unreal Engine?

I am creating an enroll request simulating a DMS in Unreal Engine 4.27. I have created a CSR file with OpenSSL, which I add to the body of the HTTPS request. Now I need to add the private key and the certificate (which I already have stored in files) to the TLS field of Unreal, but I can’t find how to do it. One of my colleagues has this code in GO where he defines the HTTPS client’s TLS configuration and there he can add the certificate and the public key, but in Unreal the HTTP client is already created by the engine’s own modules (which I am using)

How can I set this field in UE4?
