Narrow object keys only to those that have string values

Question

I'd like to narrow object's keys to only those with string value. Here's an example:

interface Person {
  id: number;
  name: string;
  address: Address;
}

type onlyKeysWithStingValues = ??? // only the key name should be allowed

Basically I'd like to narrow keyof Person to only those keys with string values. Is it possible?
