Firebase Schedule Functions giving error when deploy - node.js

Question

I was referring Firebase documentation for cloud function to schedule a function. But It was giving following error when try to deploy.
Error: Error occurred while parsing your function triggers.
token-refresh/functions/index.js:5
export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
^^^^^^

I just tried to deploy exact function that is in documentation, but it is giving error.
My Code I tried to deploy,
const functions = require('firebase-functions');
export scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
console.log('This will be run at 23.05 UTC');
});
My versions:
Firebase/ firebase-tools: 7.0.0
node: 11.11.0
npm: 6.7.0

The following should work:
const functions = require('firebase-functions');
exports.scheduledFunction = functions.pubsub.schedule('5 23 * * *').onRun((context) => {
console.log('This will be run at 23.05 UTC');
});
