For our Cypress E2E testing we are using page-objects as below (https://github.com/OWASP/wrongsecrets/blob/master/src/test/e2e/cypress/pages/homePage.js):

export default class HomePage {
  static CHALLENGE_TABLE = 'challenge-overview'
  static CHALLENGE_TABLE_ROW = 'challenge-row'
  static CHALLENGE_0_COMPLETED = '"challenge-0_completed-link"'
  static TOTAL_SCORE = 'total-score'
}

when I run eslint9, I get:

/home/runner/work/wrongsecrets/wrongsecrets/src/test/e2e/cypress/pages/homePage.js
  2:26  error  Parsing error: Unexpected token =

While my eslint.config.mjs is:

import { FlatCompat } from '@eslint/eslintrc'
import mochaPlugin from 'eslint-plugin-mocha'
import globals from "globals";
const compat = new FlatCompat()
export default [
  {
    languageOptions: {
      ecmaVersion: 2022,
      sourceType: "commonjs",
      globals:{
        ...globals.browser
      }
    },
  },
  mochaPlugin.configs.flat.recommended, {
    rules: {
      'mocha/no-exclusive-tests': 'error',
      'mocha/no-skipped-tests': 'error',
      'mocha/no-mocha-arrows': 'off'
    }
  },
  ...compat.config(
    {
      extends: ['plugin:cypress/recommended'],
      rules: {
        'cypress/no-unnecessary-waiting': 'off'
      }
    })
]

What is wrong with my eslint.config.mjs? How can I make Eslint accept static properties? Or are my static properties no longer defined properly? Can you please help me?
