Adding custom data to PRODUCT_ADD_TO_CART

[Marcoj776]

Adding custom data to an Analytics component such as ProductView is a breeze
such as:

<Analytics.ProductView
  data={{
    products: [
      {
        id: product.id,
        title: product.title,
        ....
      },
    ],
  }}
  customData={{
    isNonDtc: isNonDtc,
  }}
/>

But how do I pass custom data for the PRODUCT_ADD_TO_CART ?

As you can see from the screenshot this is the data that is passed to my analytics
subscribe('product_added_to_cart', (data) => {...})
