SkylinkJS | SkylinkJS Javascript WebRTC SDK | SDK library

I am using Skylink for video calling and I want to use in a react project. I know how to use it with Vanilla JavaScript as their demo project is at codepen But when I try to use it with react I am getting some errors. Here is how I tried:

1. Installed the package from npm using Yarn.
2. Imported the package import SkyLink from 'skylinkjs'
3. Then called the function constructor const skylink = new SkyLink(); But I get the following error:

Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_3_skylinkjs___default.a is not a constructor

If I try to import like this:

import {SkyLink} from 'skylinkjs'; const skylink = new SkyLink();

then the error is

Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_3_skylinkjs__.SkyLink is not a constructor

and If I try to import all from the module and then call the function costructor:

import * as SkyLink from 'skylinkjs'; const skylink = new SkyLink();

the error will be this Uncaught TypeError: __WEBPACK_IMPORTED_MODULE_3_skylinkjs__ is not a constructor

Can you please tell me what am I doing wrong?
