Configuring an AuthzClient with a truststore

The AuthzClient#create() method reads a keystore.json file into a Configuration object. Configuration extends AdapterConfig and inherits fields/properties like truststore, truststorePassword, disableTrustManager as well as few others which are seemingly meant for fine-tuning the underlying HttpClient.

These fields/properties are consistent with the Java adapter config and are also mentioned in the Authorization Services Guide: Configuring TLS/HTTPS.

However from a quick experimentation and a cursory glance in the keycloak-authz-client source code it seems that these Configuration fields are actually ignored and there is no way to configure a trustore for the AuthzClient using a keystore.json file.

Is this correct?
