sealed class support

Hey, thanks for this project, so far it looks great but I am running into some limitations with sealed classes. I have a model as follows:

data class Tablet(
    val id: String,
    val something: Something,
    val apps: Map<String, App>
)

where-as app is a sealed class and while jackson 2.10.1 recognises that and converts incoming requests perfectly fine in the generated json schema App is only displayed as an empty object. Are sealed classes meant to be supported? As far as I can tell that would probably map to a oneof, right?

Edit: For reference, here is btw the PR that added auto-discovery of sealed classes: https://github.com/FasterXML/jackson-module-kotlin/pull/240

i got it to work with:

    @JsonTypeInfo(use = JsonTypeInfo.Id.NAME)
    @JsonSubTypes(
            JsonSubTypes.Type(Base.A::class, name = "a"),
            JsonSubTypes.Type(Base.B::class, name = "b"),
            JsonSubTypes.Type(Base.C::class, name = "c")
    )
    sealed class Base {
        class A(val str: String) : Base()
        class B(val i: Int) : Base()
        class C(val l: Long) : Base()
    }
