How Can I Call HTTPS Function With 'firebase Functions:shell'?

I don't understand how to call HTTPS functions in local.

I made index.js file and exported hello functions and run firebase functions:shell.

I read this document, and I followed this way:

https://firebase.google.com/docs/functions/local-shell#invoke_https_functions

# invoke
myHttpsFunction()
myHttpsFunction.get()
myHttpsFunction.post()

but I got this message hello is not defined

This is index.js I wrote.

const admin = require('firebase-admin')
const {https} = require('firebase-functions')

admin.initializeApp()

exports.hello = https.onRequest((_, response) => {
  response.end('hello')
})

This is terminal.

$ firebase functions:shell
✔  functions: Using [email protected] from host.
✔  functions: Emulator started at http://localhost:5001
i  functions: Watching "/Users/xxx/xxx" for Cloud Functions...
⚠  Default "firebase-admin" instance created!
i  functions: HTTP trigger initialized at http://localhost:5001/xxx/us-central1/hello
i  functions: HTTP trigger initialized at http://localhost:5001/xxx/us-central1/callable
firebase > ⚠  Default "firebase-admin" instance created!
firebase > hello()
ReferenceError: hello is not defined

> firebase > hello() should be return hello, but hello is not defined.
