+Alternatively, you can create your own toolbar controls by passing an array of `controls` as a prop to the `BlockControls` component. Each control should be an object with the following properties:
 
 - `icon: string` - Slug of the Dashicon to be shown in the control's toolbar button
 - `title: string` - A human-readable localized text to be shown as the tooltip label of the control's button
 - `subscript: ?string` - Optional text to be shown adjacent the button icon as subscript (for example, heading levels)
 - `isActive: ?boolean` - Whether the control should be considered active / selected. Defaults to `false`.
