React-webcam enable/disable flash - reactjs

Question

I'm using react JS to create a camera application
I want to be able to save a photo snapshot, change the facingMode, to be able to use the font and back camera of the phone. Also, I would like to enable and disable the flash when the facingMode is set to the environment.
I used react-webcam from npm to start a video stream and create a snapshot.
At this point, I can flip the camera (to use the front and back camera), but can I enable/disable the flash when the back camera is active?
In here https://developer.mozilla.org/en-US/docs/Web/API/Media_Streams_API/Constraints i found a constant property called torch that is used for the mobile flash, but i don't know how to dynamycally set the vale to true/false
import React from 'react';
import Webcam from 'react-webcam';
import { useState, useRef } from 'react';
const WebcamComponent = () => <Webcam />;
const WebcamCapture = () => {
const webcamRef = React.useRef(null);
const [hasEnvCamera, setEvnCamera] = useState(false);
const [image, setImage] = useState('');
const [flash, setFlash] = useState(false);
const capture = React.useCallback(() => {
const imageSrc = webcamRef.current.getScreenshot();
setImage(imageSrc);
}, [webcamRef]);
const videoConstraints = {
width: 220,
height: 200,
facingMode: 'user',
};
const videoFlipConstraints = {
width: 220,
height: 200,
facingMode: { exact: 'environment' },
};
const changeCamera = (e) => {
e.preventDefault();
if (hasEnvCamera) {
console.log(' back camera');
setEvnCamera(false);
} else {
console.log(' front camera');
setEvnCamera(true);
}
};
const changeFlash = (e) => {
e.preventDefault();
