Difficulty creating a union of branded types using `@effect/schema`

type GenPassword = string & Brand.Brand<"GenPassword">
const GenPassword = Brand.nominal<GenPassword>()

type UserSecret = string & Brand.Brand<"UserSecret">
const UserSecret = Brand.nominal<UserSecret>()

const Secret = S.union(
  S.string.pipe(S.fromBrand(GenPassword)), 
  S.string.pipe(S.fromBrand(UserSecret))
)
