React state doesnt update, drilling seems ok though - reactjs

Question

I've got a modal that I want to be able to auto-shut itself using a drilled function. The console.log does work, but the state isn't actually updating. What am I doing wrong? Triggering the state via the dev tools works fine, so it's not the state itself. Is drilling within a component the problem?
index.js:
export default function Home() {
const [modalOpen, setModalOpen] = useState(false)
const handleModalOpen = () => {
console.log ("Setting modal to true")
setModalOpen (true)
}
const handleModalClose = () => {
console.log ("Setting modal to false")
setModalOpen (false)
}
// all the normal app body
{modalOpen ?
(<Modal handleModalClose={handleModalClose} height='30vh'>
<h4>Thank you for your contact request.</h4>
<h4>Keep in mind that this is only a demo website, not an actual business.</h4>
</Modal>): null}
</div>
)
}
Modal.js:
import { createPortal } from "react-dom";
import { useEffect, useState } from "react";
import styles from '../styles/Modal.module.css'
const Backdrop = (props) => {
return <div onClick={() => props.handleModalClose()} className={styles.backdrop} />
}
const Message = (props) => {
let width = '70vw'
let height = '80vh'
if (props.width) width = props.width
if (props.height) height = props.height
return (
<div style={{ width: width, height: height }} className={styles.message}>
{props.children}
</div>
)
}
const Modal = (props) => {
const [backdropDiv, setBackdropDiv] = useState(null)
const [modalDiv, setModalDiv] = useState(null)
useEffect(() => {
if (typeof (window) !== undefined) {
let backdropDiv = document.getElementById('backdrop')
setBackdropDiv(backdropDiv)
let modalDiv = document.getElementById('modal')
setModalDiv(modalDiv)
}
}, [])
return (
<>
{backdropDiv !== null && modalDiv !== null ? (
<>
{createPortal(<Backdrop handleModalClose = {props.handleModalClose} />, backdropDiv)}
{createPortal(<Message children={props.children} width={props.width} height={props.height} />, modalDiv)}
</>
) : null
}
</>
)
}
export default Modal
