Optional key

Hello! How can I define an array, which is also not required as an optional key? Is this the easiest way? https://discord.com/channels/957797212103016458/957804102685982740/1213198676349026355

// Goal:
{
  steps?: ...[]
}

// This still needs `steps: undefined`
steps: 
  type({
    key: "'first'",
  })
  .or({
    key: "'second'",
  })
  .array()
  .or('undefined')

// Goal:
{
  steps?: ...[]
}

// This still needs `steps: undefined`
steps: 
  type({
    key: "'first'",
  })
  .or({
    key: "'second'",
  })
  .array()
  .or('undefined')

const T = type({
 'steps?': [
    [ { key: "'first'" }, '|', { key: "'second'" } ],
    '[]',
  ],
})

const T = type({
 'steps?': [
    [ { key: "'first'" }, '|', { key: "'second'" } ],
    '[]',
  ],
})

tl;dr if the chain definition is easier for you feel free to use it Don't or undefined tho, that may have different meaning
