Define the type as an array of any attributes from an interface

Looking for a solution:

interface Details {
  id: string;
  groups: Group[];
  name: string;
  total: number;
  open: boolean;
  debug: boolean;
  demo: boolean;
  registered: boolean;
}

I'm seeking a way to create an array type with property names from the Details interface.

For example, ['total', 'open', 'demo'] should be valid.

This was my attempt:

type RequiredFields = { [key in Details]?: string };

Unfortunately, I encountered this TypeScript error:

Type 'Details' is not assignable to type 'string | number | symbol'.
Type 'Details' is not assignable to type 'symbol'.

If you can offer any guidance, I would appreciate it!
