How do export metrics using OpenTelemetry and Spring Cloud Sleuth - metrics

Question

My team is trying to get Spring Cloud sleuth to work with the Opentelemetry api. We observe that the spans, attributes (tags) and events are exported just fine to the OTEL collector.
The metrics we add are not exported with the spans (or separately) which would be our expectation.
We have the following dependencies in our project:
implementation platform('org.springframework.cloud:spring-cloud-sleuth-otel-dependencies:1.1.1')
implementation('io.opentelemetry:opentelemetry-api')
implementation('org.springframework.cloud:spring-cloud-sleuth-api')
...
implementation 'org.springframework.cloud:spring-cloud-sleuth-otel-autoconfigure'
implementation('org.springframework.cloud:spring-cloud-starter-sleuth') {
exclude group: 'org.springframework.cloud', module: 'spring-cloud-sleuth-brave'
}
implementation 'io.opentelemetry:opentelemetry-exporter-otlp:1.22.0'
The code that adds metrics is as follow:
#Autowired
private final OpenTelemetry openTelemetry;
//...
//make two attempts - one at both api's. The first is just using a NOOP meter provider unfortunately.
DoubleCounter doubleCounter = GlobalOpenTelemetry.getMeter("io.opentelemetry.example.metrics")
.counterBuilder("calculated_used_space")
.setDescription("Counts disk space used by file extension.")
.setUnit("MB")
.ofDoubles()
.build();
doubleCounter.add(2.0);
//this is using a SDK meter provider which should export metrics with the span.
DoubleCounter build = openTelemetry.getMeter("com.jysk.some-app.some-metric")
.counterBuilder("some-counter")
.setDescription("some-description")
.setUnit("pcs.")
.ofDoubles()
.build();
build.add(4.0f);
Any insight in how we get Spring Cloud Sleuth to export metrics to a configured collector. We are using the Opentelemetry Collector.
