type MaterialKey = Exclude<keyof PointCloudMaterial, 'isMaterial'

How can I remove a wider type from a union type without removing its subtypes in TypeScript?

Using the Exclude operator doesn't work. type test = Exclude // produces type test = never I can understand why "except strings" also means excluding all the string literals, but how can I obtain 'a'|'b' out of 'a'|'b'|string? If needed, assume latest TypeScript.
