* You can attach a callback function when NEOPIN Connect QR Modal is working.
* Open - You can define actions that occur when modal is opened by overriding callbacks. 
* Close - Like the open method, the actions that occur when disconnected can be used in the same way as 'open' by putting a callback function.

```javascript
import NeopinConnectQRCode from "nptconnect-qrcode-modal";

const uri = connector.uri;

/**

 */
NeopinConnectQRCode.open(uri);

/**
 *  Close QR Code Modal
 */
NeopinConnectQRCode.close();
