If you are only talking about SSL, this is between your browser and your 
Envoy instance - there is, I believe, a section under "tls_context", where 
you can specify TLS certificates and stuff, in your Envoy config yaml file. 
There's nothing you need to configure your grpc-web client for that.

Now if you want to send credentials headers through the Envoy instances to 
your backend, then you can add those as key:value pair in the "metadata" 
argument per RPC method.
