I create a type WithoutType where I Exclude an enum member:

export enum MyEnum {
  One = "one",
  Two = "two",
  Three = "three",
  Zero = "zero",
}

export type WithoutType = Exclude<MyEnum, MyEnum.Zero>;

Now I need to check if a certain value exists/matches one of the union values of the type WithoutType?

How do I do that?
