Azure Communication Services javascript sdk on SSR

Hi I've encounter below exception where my project is SSR

ReferenceError: window is not defined
at Object.<anonymous> (/Users/hyounoo/Github/CloudHospital.Front/node_modules/@azure/communication-calling/sdk.bundle.js:4:275)
at Module._compile (internal/modules/cjs/loader.js:1015:30)
at Object.Module._extensions..js (internal/modules/cjs/loader.js:1035:10)

at webpack_require (/Users/hyounoo/Github/CloudHospital.Front/build/webpack:/webpack/bootstrap:690:1)
at fn (/Users/hyounoo/Github/CloudHospital.Front/build/webpack:/webpack/bootstrap:59:1)

first, I tried to solve this with loadable but it didn't work.

Only way I could get around with this error is removing all the references related to @azure/communication-calling sdk and start the project, than add them all back.
I had to remove the references even my redux stores.

Is this intended or will be fixed soon?
