How to use the @node-wot/binding-coap.CoapsClientFactory function in @node-wot/binding-coap

console.dir(this.config);
        
        // http server for local control and monitoring
        let httpServer = (typeof this.config.http.port === "number") ? new HttpServer(this.config.http.port) : new HttpServer();
        this.addServer(httpServer);

        // remote proxy bridges
        if (this.config.fujitsu) this.addServer(new FujitsuServer(this.config.fujitsu.remote));
        if (this.config.oracle) this.addServer(new OracleServer(this.config.oracle.store, password));

        // clients for consuming
        this.addClientFactory(new FileClientFactory());
        this.addClientFactory(new HttpClientFactory(this.config.http));
        this.addClientFactory(new HttpsClientFactory(this.config.http));
        this.addClientFactory(new CoapClientFactory());
        this.addClientFactory(new CoapsClientFactory());
    }

}
