Unhandled Rejection (TypeError): Cannot read property 'isReactComponent' of undefined

I just updated library version from 2.0.7 to 2.4.0 and started getting the error in title.

Unhandled Rejection (TypeError): Cannot read property 'isReactComponent' of undefined
/src/utils/validators.js:12 (or here https://github.com/teodosii/react-notifications-component/blob/master/src/utils/validators.js#L12)

i've found some other discussion in a different component that looks similar. there is a fix there and some explanation.
TanStack/table#1502
TanStack/table#1503

i am not sure if it helps to solve anything or i am having different issues.
if needed - i can make Pull-Request here.

for now i will roll back to the old version

Fixed in 3.0.0
