Delete local attributes instead of global attributes

Hi,

I made a mistake by importing attributes the wrong way, this is resulting in wrong attributes for a lot of products

The attributes that i added are imported as local custom attributes on each product (so not global attributes as seen in the backend -> Products -> Attributes)

Is there a way to bulk delete these local attributes for all products? For now i hide them on front-end with this code but this is a quick fix.

/**
 * Hide specific attributes from the Additional Information tab on single
 * WooCommerce product pages.
 *
 * @param WC_Product_Attribute[] $attributes Array of WC_Product_Attribute objects keyed with attribute slugs.
 * @param WC_Product $product
 *
 * @return WC_Product_Attribute[]
 */
function mycode_hide_attributes_from_additional_info_tabs( $attributes, $product ) {

	/**
	 * Array of attributes to hide from the Additional Information
	 * tab on single WooCommerce product pages.
	 */
	$hidden_attributes = [
		'nameofmyattributethatswork',
	];

	foreach ( $hidden_attributes as $hidden_attribute ) {

		if ( ! isset( $attributes[ $hidden_attribute ] ) ) {
			continue;
		}

		$attribute = $attributes[ $hidden_attribute ];

		$attribute->set_visible( false );
	}

	return $attributes;
}

add_filter( 'woocommerce_product_get_attributes', 'mycode_hide_attributes_from_additional_info_tabs', 20, 2 );
