How can I make custom Option types work with graphql-kotlin?

[mainrs]

I am using ArrowKt, which defines a custom arrow.option.Option<T> type. I'd like to make it map to either T, if present, or null if no value is present.

Is there some way to make this library work with the ArrowKt types?

In general, you would need to modify schema generation process so it can understand how to represent Option in the schema (see schema generator hooks) and then you would also need to modify runtime process so you can correctly unwrap it (i.e. provide custom DataFetcher).
