Push metrics using Kafka Exporter with OpenTelemetry

Question

I am trying to collect some metrics and export it to Kafka using OpenTelemetry. For a simple POC, I have a local file in the OpenMetrics format and I wish to parse it and push the metrics on Kafka.

I understand I should use kafkaexporter but I am not able to understand how the end-to-end flow would look like. A code snippet would be really helpful.

I am creating the Kafka exporter using the following code:

func newExporter(ctx context.Context) (exporter.Metrics, error) {
    f := kafkaexporter.NewFactory(kafkaexporter.WithMetricsMarshalers())
    cfg := f.CreateDefaultConfig()
    ts := component.TelemetrySettings{
        Logger:          logger,
        MeterProvider:   meterProvider(),
        MetricsLevel:    configtelemetry.LevelNormal,
    }
    cs := exporter.CreateSettings{
        ID:               component.NewID("metrics"),
        TelemetrySettings: ts,
        BuildInfo:        component.NewDefaultBuildInfo(),
    }

    return f.CreateMetricsExporter(ctx, cs, cfg)
}

func meterProvider() *metric.MeterProvider {
    return metric.NewMeterProvider()
}

Now say I have a few counters / gauge meters, how do I push it using the above exporter?
