Hey for `polymorphism` it currently uses the `type` attribute. Is there any way to change the name? In my case I need it to look at the `name` attribute (which is the same as `type` just different name)

you can specify custom `classDiscriminator` (defaults to `type`)

```val format = Json {
    classDiscriminator = "__typename"
}```

ah so you can only do that globally on serializer level?

haven't seen anything that would limit it to just specific polymorphic serializer

this info is currently missing from <https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/polymorphism.md> (it doesn't mention `classDiscriminator` either)

*it is mentioned under <https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/json.md#class-discriminator>
