[REQUIRED] Describe the problem

When I try to get the Storage DownloadURL with Nodejs, the getDownloadURL function works fine, but Nodejs doesn't finish running.
firebase-js-sdk should support the Nodejs environment.
https://firebase.google.com/docs/web/environments-js-sdk

Steps to reproduce:

Run the following code in Nodejs (14.18.0).
In my environment, Download URL is output normally, but Nodejs execution does not finish.

Relevant Code:

'use strict'const{ initializeApp }=require('firebase/app')const{ getStorage, ref, getDownloadURL }=require('firebase/storage')initializeApp({apiKey: '',authDomain: '',projectId: '',storageBucket: '',messagingSenderId: '',appId: '',measurementId: ''})!(async()=>{conststorage=getStorage()constpathReference=ref(storage,'sample.txt')consturl=awaitgetDownloadURL(pathReference)console.log(url)})()
