Avoid exposure of API key and client ID when using Google Classroom browser API

问题

I'm trying to use the Google Classroom Browser API. I referred to the page at https://developers.google.com/classroom/quickstart/js for the Quick Start for this API, but unfortunately it seems to expose my Client ID and API key in the script within the HTML.

Here's a link to the sample page provided by Google: https://github.com/gsuitedevs/browser-samples/blob/master/classroom/quickstart/index.html

The Client ID and API key are exposed on lines 34 and 35:

// Client ID and API key from the Developer Console
var CLIENT_ID = '<YOUR_CLIENT_ID>';
var API_KEY = '<YOUR_API_KEY>';

Is there any way I can use the Google Classroom Browser API without exposing my Client ID and API key? If not, how can I secure them and prevent unauthorised usage by anyone else?
