How to properly type a method decorator?

Question

typescript

Good afternoon. Tell me how to type the Compute method

class SomeClass {
 foo: string;
 bar: string

@Compute(['foo', 'bar'])
  fooBar({
    foo,
    bar,
  }): void {}
}

export function Compute<
  T extends { [key: string]: any;  },
  K extends keyof T = keyof T
>( reactiveInputs: K[], reactiveDependency: K[] = [] ): (
  target: T,
  propertyKey: string,
  descriptor: TypedPropertyDescriptor<(newValues: Pick<T, K>) => void>
) => any {
  return (target, name, descriptor) => {}
}

Doesn't work for me 1) Elements of decorat argument array should be pulled from property class. 2) The argument (object) of the fooBar method must have its keys matching the elements of the array from the decorator.
