Massaging returned data

Help

Given this create user if not exist query:

Let(
  {
    match: Match(Index('users_by_email'), 'foo@bar.biz'),
    data: { email: 'foo@bar.biz' },
    password: 'foobar',
  },
  If(
    Exists(Var('match')),
    {
      type: 'createUser',
      data: { message: 'User already exists' },
    },
    Create(Collection('Users'), {
      data: Var('data'),
      credentials: { password: Var('password') },
    }),
  ),
)

If the user exists, it will return:

{ type: 'createUser', data: { message: 'User already exists' } }

If not, it will create it and come back with:

{
  ref: Ref(Collection("Users"), "327348265972400640"),
  ts: 1648442483850000,
  data: { email: 'foo@bar.biz' }
}

How I can tap into Create return value? After creating the user I would like to return something like:

{
  type: 'createUser',
  data: {
    email: 'foo@bar.biz',
    id: '327348265972400640'
  }
}

You can nest Let functions. Instead of just Create, do something like:

Let(
  {
    created: Create(
      Collection('Users'),
      {
        data: Var('data'),
        credentials: { password: Var('password') },
      }
    ),
  },
  {
  ... whatever you want to return here ...
  }
)
