I am seeing a a red underline when I'm using an optional chain, but the code runs fine as I am on node 14

Here's my setup:

node 14.1.0
eslint "^6.8.0"

.eslintrc.js

module.exports = {
    "env": {
        "node": true
    },
    "extends": [
        "eslint:recommended",
    ],
    "parserOptions": {
        "sourceType": "module",
        "ecmaVersion": 2020
    },
    "rules": {
    },
}
