Changing Schema Type for Product

The following seems to still output the structured data:

function filter_woocommerce_structured_data( $markup ) {
	$markup['@type'] = "Product";
}

add_filter( 'woocommerce_structured_data_product', 'filter_woocommerce_structured_data', 10, 2 );

How do I go about changing the product type to another type such as Book? Changing the value to anything other than “Product” like below, seems to break the structure output entirely.

function filter_woocommerce_structured_data( $markup ) {
	$markup['@type'] = "Book";
}

add_filter( 'woocommerce_structured_data_product', 'filter_woocommerce_structured_data', 10, 2 );
