If you need to use functionalities from two coroutine scope func- tions, you need to use one inside another. For instance, to set both a timeout and a dispatcher, you can use withTimeoutOrNull inside withContext. - Kotlin Coroutines Deep Dive

suspend fun calculateAnswerOrNull(): User? =
    withContext(Dispatchers.Default) {
        withTimeoutOrNull(1000) {
            calculateAnswer()
        }
}
