Opentelemetry logs not printing - spring-boot

Question

I am migrating from open tracing to open telemetry with jaeger.
Earlier the pom had following:
<dependency>
<groupId>io.opentracing</groupId>
<artifactId>opentracing-api</artifactId>
<version>0.31.0</version>
</dependency>
<dependency>
<groupId>io.opentracing.contrib</groupId>
<artifactId>opentracing-spring-cloud-starter</artifactId>
<version>0.1.13</version>
</dependency>
<dependency>
<groupId>io.jaegertracing</groupId>
<artifactId>jaeger-client</artifactId>
<version>0.31.0</version>
</dependency>
Then I migrated from java 8 spring boot v2.3 to java 17 spring boot v3. So I updated the config as follows:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-brave</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-otel-autoconfigure</artifactId>
</dependency>
<dependency>
<groupId>io.opentelemetry</groupId>
<artifactId>opentelemetry-exporter-otlp-trace</artifactId>
<version>1.14.0</version>
</dependency>
<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-okhttp</artifactId>
<version>1.51.0</version>
</dependency>
the properties are mentioned below:
<java.version>17</java.version>
<spring-boot.version>3.0.0</spring-boot.version>
<spring-cloud.version>2021.0.5</spring-cloud.version>
<spring-cloud-sleuth-otel.version>1.1.0</spring-cloud-sleuth-otel.version>
<opentelemetry-exporter-otlp>1.20.1</opentelemetry-exporter-otlp>
The problem I encounter is that the spans are not logged. I do not see any logs that say span reported, which I usually get before. I haven't connected this to any collector or added any telemetry related configuration. I was following this tutorial () but it says the app should work out of the box.
What kind of configurations am I missing here?
EDIT: The second approach (The open telemetry one) works when spring boot version is 2.5.6 (https://qdnqn.com/opentelemetry-spring-boot-kafka-and-jaeger-in-action/) but not when 3.0. How can make this work in spring boot 3?
