How to set a custom type for context in v1.13?

[fcsha]

In ky v1.12, this worked fine:

declare module 'ky' {
  interface Options {
    context?: MyContext;
  }
  interface NormalizedOptions {
    context?: MyContext;
  }
}

After upgrading to v1.13, I get this error:

Subsequent property declarations must have the same type. Property ‘context’ must be of type ‘Record<string, unknown>’, but here has type ‘MyContext | undefined’.ts(2717)

The Ky context option is intentionally untyped. If you want your own, you have to use a different name.
