Make key of TObject be optional

[woody146]

I have the function

import { TObject, TString, Type } from '@sinclair/typebox';
export function check<T extends Record<string, any>>(
  object: T,
  type: TObject<{ [K in keyof T]: TString }>
) {
  console.log(object, type);
}

check({ a: 1, b: 2 }, Type.Object({ a: Type.String(), b: Type.String() }));

When I type check({ a: 1, b: 2 }, Type.Object, it will suggest properties (a or b) and require both a and b properties.

But now I call check() with object { a: 1, b: 2 }, I want it will suggest properties (a or b) and require only a or b.
I fix function to

export function check<T extends Record<string, any>>(
  object: T,
  type: TObject<{ [K in keyof T]?: TString }> // throw error Type 'undefined' is not assignable to type 'TSchema'
) {
  console.log(object, type);
}

How do I resolve it?
