I added the google icon CDN to my _document.js file nextJs project, but still google icons are not working in my project.
```import { Html, Head, Main, NextScript } from "next/document";
export default function Document() {
return (
<Html>
<Head>
<link
href="https://fonts.googleapis.com/icon?family=Material+Icons"
rel="stylesheet"
/>
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
); }
