It doesn't work :(

StreamsBasedServer.scala:25:56
value open is not a member of object zio.nio.channels.AsynchronousServerSocketChannel
server <- AsynchronousServerSocketChannel.open

StreamsBasedServer.scala:39:22
Found: (server.accept : Exception zio.nio.channels.AsynchronousSocketChannel)
Required: zio.ZIO[zio.Scope & Nothing, Any, Any]
.scoped(server.accept)

StreamsBasedServer.scala:47:15
cannot resolve reference to type zio.duration.package.type.Duration
the classfile defining the type might be missing from the classpath
channel.readChunk(64).tap(_ => Console.printLine("Read chunk")).orElse(ZIO.fail(None))

StreamsBasedServer.scala:54:24
value close in class AsynchronousByteChannel cannot be accessed as a member of (channel : zio.nio.channels.AsynchronousSocketChannel) from module class StreamsBasedServer$.
_ <- channel.close
