How do vue functional components load asynchronously?

<script>
import { aaa } from "./aaa";
...
import { nnn } from "./nnn";

export default {
    data() {
        return {
            funMap: new Map()
        };
    },
    computed: {
        rme() {
            return this.$bus.rme;
        },
    },
    watch: {
        rme() {
            this.setRME();
        },
    },
    created: function() {
        this.funMap.set("aaa", aaa);
        ...
        this.funMap.set("nnn", nnn);
    },
    methods: {
        setRME() {
            this.funMap.get(this.rme)({
                xxx: "xxx",
            });
        },
    }
};
</script>

how can I use asynchronous loading for this structure?
