Preset value for composer field for FormKit

Development

How can I preset a value for the composer field in FormKit? The following does not work:

<form.Field
  @name="content"
  @validation="required"
  @title="&nbsp;"
  @type="composer"
  @value={{this.rawPost}}
  as |field|
>
  <field.Control @preview={{true}} />
</form.Field>

With the help of Ask, seems like I just needed to do this:

<Form
+  @data={{hash content=this.rawPost}}
   @onSubmit={{this.handleSubmit}}
   as |form|
