When using LocalizedLink Typescript requires property 'language' witch sould be an optional propery based on your example.

issue is on index.d.ts

export function LocalizedLink({ to, language, ...props }: {
  [x: string]: any;
  to: any;
  language: any; /* this sould be optional "language?: any" */
}): JSX.Element;

TS2741: Property 'language' is missing in type '{ children: ReactNode; to: string; className: string; }' but required in type '{ [x: string]: any; to: any; language: any; }'.
