I'm using two ZIO scope blocks in my codebase one of them is for creating commands and the other for listening if an event published. When the command and the listener are in the same code block and run sequentially, there is no problem, but when they are run in different time intervals, the listening side does not receive information. How can I solve this?

There is a pub/sub mechanism or it's reading from the database?

Command code block like this example; https://github.com/hnaderi/edomata-example/blob/05609b7f54388dae89b9a925eea21b794db9fd39/core/src/main/scala/dev/hnaderi/example/Main.scala#L47

Listening code block

def mySink(app: Application[Task]) = ZSink.foreach((item: OutboxItem[Notification]) =>
  for {
    _ <- printLine("mySink: " + item)
    _ <- app.accounts.storage.outbox.markAsSent(item)
  } yield ()
)

def printOutbox(app: Application[Task]) = app.accounts.storage.outbox.read.toZStream().run(mySink(app))

ZIO.scoped {
 for {
   app <- Application[Task]().toScopedZIO
   _ <- printOutbox(app)
  } yield ()
 }..fork
