Equivalent usage of Simpleclient in micrometer-registry-prometheus `1.13.x`

1.13 Migration Guide と、issue で言及されている PrometheusMeterRegistry、Collector、MetricFamilySamples、TextFormat API から始めてください。現在の client_java のバージョンで対応する API を追跡し、3 つすべてのシナリオについて、必要なコード変更を含む移行時の置き換え方法を文書化してください。移行ガイドでこれらの置き換えが明確に説明されていれば完了です。

Hi Team! We are migrating our project from micrometer-registry-prometheus:1.12.8 to version 1.13.8 . I see that the io.prometheus:simpleclient:jar:0.16.0 has been deprecated.

We have few scenarios which I do not see in the migration guide.

Here are few scenarios,

1. What is the equivalent of io.prometheus.client.Collector.MetricFamilySamples and the MetricFamilySamples.Sample

   PrometheusMeterRegistry instance = new PrometheusMeterRegistry(PrometheusConfig.DEFAULT);
   MetricFamilySamples samples =  instance.getPrometheusRegistry().metricFamilySamples()

 if (sample == null || sample.name == null || sample.labelNames == null || sample.labelValues == null) {
      LOGGER.error("The provided Sample object is either null or one of its fields is null: {}", sample);
      throw new IllegalArgumentException("The provided Sample object is either null or one of its fields is null: " + sample);
    }

2. Is the import io.prometheus.metrics.model.registry.Collector a replacement of io.prometheus.client.Collector, however, I couldn't find the below in the new Collector.

Enumeration<Collector.MetricFamilySamples> metricFamilySamples;

3. Similarly how we can replace the io.prometheus.client.exporter.common.TextFormat?

Could you please help me with the code changes. Also, can you share any additional docs available that we can follow for migrating from the usage of simpleclient.
