How to define the type of object's key using same object's another key in TypeScript?

Question

Consider following pseudo type signature for TypeScript:

import { z, ZodObject, ZodRawShape } from 'zod';

export type DefinitionObject<T extends ZodRawShape> = {
  validator: ZodObject<T>;
  htmlFn: (value: z.infer<typeof validator> & { locale?: string; }) => JSX.Element;
};

The type of htmlFn key depends on type of validator key via typeof validator. But of course, TypeScript errors with:

Cannot find name 'validator'.ts (2304)
Parameter 'value' of exported function has or is using private name 'validator'.ts (4078)

So, I need something like this.validator inside the type signature context. How can I achieve this?
