How to open APK file and install?

My code:

import RNFS from 'react-native-fs';

const downloadDest = `${RNFS.CachesDirectoryPath}/${(Math.random() * 1000) | 0}.apk`;
const options = {
    fromUrl: url,
    toFile: downloadDest,
    background: true,
};
RNFS.downloadFile().promise.then(res => {
  // How to open APK file and install?
})

How do I open an APK file and install it?

I have tried using Linking.openURL (downloadDest) but that didn't work.
