Extract common objects from sealed class in kotlin

Question

I have two data classes e.g.

sealed class API1Status {
    data class Success(
        val name: String
    ) : API1Status()

    sealed class Error : API1Status() {
        object API1FAiled : Error()
        object SystemError : Error()
        object ServerError : Error()
        object InvalidRequest : Error()
    }
}

sealed class API2Status {
    data class Success(
        val name: String
    ) : API2Status()

    sealed class Error : API2Status() {
        object API2FAiled : Error()
        object SystemError : Error()
        object ServerError : Error()
        object InvalidRequest : Error()
    }
}

As you have noticed, I have 3 errors common between both sealed classes, namely.

object SystemError : Error()
object ServerError : Error()
object InvalidRequest : Error()

I would like to know how to extract these errors out of the sealed classes to be used across the sealed classes.
