what’s wrong with the way I define this type

type Payload<Es> = {
  trigger:
    Es extends Record<infer K, infer V>
     ? { key: K, data: V } : never
}

type Evs = {
  "item.1": { ok: "Y", code: number }
  "item.2": 1 | 0
}
const payload: Payload<Evs> = {
  trigger: {
    key: "item.1",
    data: 1
  }
}

payload.trigger.data doesn’t get inferred as I expect

expected

{ ok: "Y", code: number }

what I get

0 | { ok: "Y", code: number } | 1
