You can use the react-native-keyevent package for react native.

componentDidMount() {
KeyEvent.onKeyDownListener((keyEvent) => {
    if (keyEvent.keyCode === 'Keycode of the power button'){
        this.timeout = setTimeout(() => {
            //Your SOS Function here
        }, 1000)
    }
});

KeyEvent.onKeyUpListener((keyEvent) => {
    if (keyEvent.keyCode === 'Keycode of the power button'){
        clearTimeout(this.timeout)
    }
    })
}

componentWillUnmount() {
  KeyEvent.removeKeyDownListener();
  KeyEvent.removeKeyUpListener();
}

    @Override
public boolean dispatchKeyEvent(KeyEvent event) {
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK
    || event.getKeyCode() == KeyEvent.KEYCODE_VOLUME_UP
    || event.getKeyCode() == KeyEvent.KEYCODE_VOLUME_DOWN
    || event.getKeyCode() == KeyEvent.KEYCODE_POWER) {
        Log.i("Key", "keycode " + event.getKeyCode());
        return true;
    }
    
    return super.dispatchKeyEvent(event);
}
