ReferenceError: navigator is not defined (Next.js, Phaser)

Have anyone encountered something similar before? I'm trying to integrate Phaser into a next.js app. But whatever I do, I get this error:

error - ReferenceError: navigator is not defined

Code:

import { Phaser} from "phaser"


export default function Test() {
  const config = {
    type: Phaser.AUTO,
    width: 800,
    height: 800,
  };

Do you have any idea where the problem is?
