I left some comments.
Out of curiosity, what's the use case to provide a union type? I would usually say to create a new action, but now I'm interested 🙂

Out of curiosity, what's the use case to provide a union type?

The author of the code is being creative 😎
E.g. a limited list of strings are allowed, e.g. 'A', 'B', 'C' and 'D', which serve as a particular differentiator for the object, lets call it type SomeKind
When one of the kinds would require additional info, such as extraRequiredProp 🙂
