I have this JSON:

const example = {
  admin: {
    name: "Name",
  },
  greeting: "Hello",
};

I can get the main keys in TS like this:

type Keys = keyof typeof example;

I can write a function like this:

const myFunc = (key: Keys)=>{
    ///...
}

And I can call it like this:

myFunc('admin')

And I cannot call it like this:

myFunc('Non-existing key')

How can I write a function like the following and enjoy VS Code’s intellisense, so that it would give me suggestion for name?

myFunc('admin.name')
// OR
myFunc('admin', 'name')
