如何在java中将Mono<List>对象转换为简单列表对象？

import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        Mono<List<Integer>> monoList = Mono.just(List.of(1, 2, 3, 4, 5));

        Mono<List<Integer>> simpleListMono = monoList.flatMapMany(Flux::fromIterable)
                .collectList();

        simpleListMono.subscribe(System.out::println);
    }
}
