QR Modal usage

class ModalAdapter {
    constructor(opts) {
        this.pubSub = TypedEventEmitter;
        this.pubSub.on('close', () => {
            this.close();
            opts.onClose();
        });
    }

    close () {
        const wrapper = document.getElementById('qr-modal');

        if (wrapper) {
            document.body.removeChild(wrapper);
        }
    }

    open(msg) {
        const wrapper = document.createElement('div');
        wrapper.setAttribute('id', 'qr-modal');

        document.body.appendChild(wrapper);

        ReactDOM.render(
            <div className="modal">
                <button onClick={() => this.pubSub.emit('close')}>Close</button>
                {isMobile ? (
                    <a href={`tcwb://ws?uri=${msg.connect_string}`}>Wallet connect</a>
