hi,
how can I choose a type based on a string parameter,
for example I have such object for type A:

{
  "type": "A",
  "field": "foo"
}

and such for type B:

{
  "type": "B",
  "foo": "bar"
}

how to differentiate @Serializable classes based on the type field?
the classes I currently have are as follows:

@Serializable
sealed class Message {
    @Serializable data class A(field: String, type: String): Message()
    @Serializable data class B(foo: String, type: String): Message()
}

you have to specify classDiscriminator

actually it defaults to type anyway
