Diversamente da Worker, questo codice non viene eseguito sull'Executor specificato nella configurazione di WorkManager.
override suspend fun doWork(): Result = withContext(Dispatchers.IO) {
Raramente è necessario cambiare il Dispatcher che CoroutineWorker sta usando e Dispatchers.Default è una buona opzione per la maggior parte dei casi.
