Works on windows.

            var producerConfiguration = configuration.GetSection("ApacheKafka:Publisher").AsEnumerable(true);

            ProducerConfig pc = new ProducerConfig(producerConfiguration.ToDictionary<string, string>());
            pc.SaslOauthbearerTokenEndpointUrl = "<url>";
            pc.SaslOauthbearerClientId = "<client-id>";

            _producer = new ProducerBuilder<string, string>(pc)
                .Build();
