Error when assigning `Option.none` to `test` property in type `T`

Hi there, would anyone know why this is erroring? I'm trying to have incorrect state unrepresentable, but looks like

Option.none

Option.none

Option.none

Option.none has

Option

Option

Option

Option type instead of

None

None

None

None. Am I doing it wrong?

type T = { _tag: 'WithSome', test: Option.Some<number> } | { _tag: 'WithNone', test: Option.None<number> };

const thisErrors: T = {
  _tag: 'WithNone',
  test: Option.none<number>()
}

type T = { _tag: 'WithSome', test: Option.Some<number> } | { _tag: 'WithNone', test: Option.None<number> };

const thisErrors: T = {
  _tag: 'WithNone',
  test: Option.none<number>()
}

type T = { _tag: 'WithSome', test: Option.Some<number> } | { _tag: 'WithNone', test: Option.None<number> };

const thisErrors: T = {
  _tag: 'WithNone',
  test: Option.none<number>()
}

type T = { _tag: 'WithSome', test: Option.Some<number> } | { _tag: 'WithNone', test: Option.None<number> };

const thisErrors: T = {
  _tag: 'WithNone',
  test: Option.none<number>()
}
