I have the following files:

interface FcmDataNotifier {

    // ...
}

interface FcmDataProvider {
    // ...
}

interface FcmCore : FcmDataNotifier, FcmDataProvider

internal class FcmCoreImpl @Inject constructor() : FcmCore {

And the following module:

@Module
@InstallIn(SingletonComponent::class)
internal abstract class FcmModule {

    @Singleton
    @Binds
    abstract fun bindFcmCore(
        impl: FcmCoreImpl
    ): FcmCore

    companion object {

        @Provides
        @Singleton
        fun provideFcmDataNotifier(
            fcmCore: FcmCore
        ): FcmDataNotifier {
            return fcmCore
        }

        @Provides
        @Singleton
        fun provideFcmDataProvider(
            fcmCore: FcmCore
        ): FcmDataProvider {
            return fcmCore
        }
    }
}

But for some reason I don’t know, I’m receiving the following error:

FcmDataProvider cannot be provided without an @Provides-annotated method.

What am I possibly configuring wrong?
