While importing daypilot lite getting the error :Type 'typeof DayPilot' is not assignable to type 'any[] | Type<any> | ModuleWithProviders<{}>

Question

i installed daypilot-lite-angular library but when i tried to import it in my app.module it threw me an error like this:

"Type 'typeof DayPilot' is not assignable to type 'any[] | Type<any> | ModuleWithProviders<{}>'"

while importing in the app.module:

import { DayPilot } from "@daypilot/daypilot-lite-angular";

i tried to enter the "DayPilot " in the import line or the declaration but both gives the same error. anybody knows what causes that?
