Spring Boot 3 Upgrade Executor context propagation sleuth to micrometer tracing

Question

I am migrating my project from Spring boot version 2.7.4 to version 3.2.2. i need to use micrometer instead of sleuth how should I edit the "Executor" BEAN I mentioned below for asynchronous?
What should I use instead of LazyTraceExecutor class?

@Bean("asyncExecutor")
    public Executor getAsyncExecutor(BeanFactory beanFactory) {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setWaitForTasksToCompleteOnShutdown(true);
        executor.setThreadNamePrefix("Async-");
        executor.setTaskDecorator(new ContextDecorator());
        executor.initialize();

        return new LazyTraceExecutor(beanFactory, executor);
    }

I rewrote the configuration as follows:

1. I left the creation of ThreadPoolTaskExecutor

@Configuration
public class AppConfiguration {

    @Bean
    public ThreadPoolTaskExecutor micrometerThreadPoolTaskExecutor(AppProperties appConfig) {
        return new TaskExecutorBuilder()
                        .maxPoolSize(appConfig.getThreadPoolMaxSize())
                        .corePoolSize(appConfig.getThreadPoolCoreSize())
                        .threadNamePrefix(appConfig.getThreadPoolPrefix())
                        .build();
    }
}

2. Micrometer tracing configuration

@Configuration(proxyBeanMethods = false)
public class TracingAsyncConfiguration implements AsyncConfigurer {

    private final ThreadPoolTaskExecutor micrometerTaskExecutor;

    public TracingAsyncConfiguration(@Qualifier("micrometerThreadPoolTaskExecutor") ThreadPoolTaskExecutor micrometerTaskExecutor) {
        this.micrometerTaskExecutor = micrometerTaskExecutor;
    }

    @Override
    public Executor getAsyncExecutor() {
        return ContextExecutorService.wrap(micrometerTaskExecutor.getThreadPoolExecutor(), ContextSnapshotFactory.builder().build()::captureAll);
    }
}
