Hello,
I need to write custom serializer for my type, which delegates most of serialization logic to generated basic serializer.

@Serializable 
data class Xxx(...)

object XxxSerializer : KSerializer<Xxx> {
    private val delegate = Xxx.serializer()
... custom serialize/deserialize logic using delegate
}

val json = Json {
serializersModule = SerializersModule { contextual(Xxx::class, XxxSerializer) }
}

json instance is being used for Retrofit converter factory which performs deserialization with json.serializersModule.serializer(type).
This code picks default serializer instead of custom one, because Xxx
has @Serializable annotation.

Is it possible to force runtime to use contextual serializer for this class?
Seems like @UseContextualSerialization should help, but I couldn't figure out correct syntax.
