API calls using Service account credentials

Thanks for stopping by to ask us a question! Please make sure to include:
I am trying to make an API call using Service account credentials method in node backend

- async function main () {
const auth = new google.auth.GoogleAuth({
keyFile: 'mumzworldgoogle.json',
// Scopes can be specified either as an array or as a single, space-delimited string.
scopes: ['https://www.googleapis.com/auth/calendar.events']
});
const authClient = await auth.getClient();

// obtain the current project Id
const project = await auth.getProjectId();

// Fetch the list of GCE zones within a project.
const res = await compute.zones.list({ project, auth: authClient });
console.log(res.data);
}
router.get('/googleAPI', async (req, res) => {
main().catch(console.error);
})

I am getting an error TypeError: google.auth.GoogleAuth is not a constructor
