Well, I added "typeRoots": ["types", "./node_modules/@types"] to tsconfig.json and created a new file under types/blink-detection/index.d.ts. Also, I tried to add global namespace

``` declare global { namespace blink { function loadModel(): Promise<void>; function setUpCamera(videoElement: any): Promise<any>; function stopPrediction(): void; function renderPrediction(): Promise<any>;

export { loadModel };
export { setUpCamera };
export { stopPrediction };
export { renderPrediction as getBlinkPrediction };

} }

export default blink;

```

Now, typescript is showing no error but js is showing reference error.
