How can one declare the return type for a Formula that returns an Array of Objects, say like:

```auto
[{'id': 'abc123', 'name': 'alice'}, {'id': 'xyz789', 'name': 'bob'}, ...]

```

I’m guessing you specify in the `addFormula` param object:

```auto
  ...
  resultType: coda.ValueType.Array,
  items: { type: coda.ValueType.Object },
  ...

```

But where can you specify that the items have a schema `mySchema`?

Found it:

`items: mySchema`

(I was doing `items: {type: mySchema}`)

May want to document this better in the usage, had to dig to this reference page to find it: [Type alias: ArrayFormulaDef - Coda Pack SDK](https://coda.github.io/packs-sdk/reference/sdk/types/ArrayFormulaDef/)

Ya, this tripped me up at first too. I’ll make sure we document this more clearly.
