Nested parameters.

@type t() :: %Stripe.Params.Checkout.SessionCreateParams.Permissions{
  update_shipping_details: String.t() | nil
}
```

* `update_shipping_details` - Determines which entity is allowed to update the shipping details.

Default is `client_only`. Stripe Checkout client will automatically update the shipping details. If set to `server_only`, only your server is allowed to update the shipping details.

When set to `server_only`, you must add the onShippingDetailsChange event handler when initializing the Stripe Checkout client and manually update the shipping details from your server using the Stripe API. Possible values: `client_only`, `server_only`.
