Firestore trigger not working when run in emulator

I'm new to Firebase and tried following this video.

code:

const functions = require("firebase-functions");
const admin = require("firebase-admin");
admin.initializeApp()
const db = admin.firestore()
exports.onUserCreate = functions.firestore.document('users/{userId}').onCreate(async(snapshot, context) => {
const values = snapshot.data()
await db.collection('logging').add({description: `Email was sent to user with username:${values.username}`}) })

This should create a new collection called 'logging' whenever a new collection is created. But the trigger doesn't work in emulator, it shows only the collection which we created.

It looks like my comment was helpful, posting it as an answer for visibility.

A new collection is automatically created when you create a new document using the set() method.

There is no separate method for creating collections. Try adding a document as described in the docs. For example,

await db.collection('logging').doc('journal').set(data);
