How to filter the 'Event Cart' text to use something else in its place, in this example just 'Cart'

example.php

<?php //Please do not include the opening PHP tag if you already have one.

function tw_ee_return_cart() {
	return 'Cart';
}
add_filter( 'FHEE__EED_Multi_Event_Registration__set_definitions__event_cart_name', 'tw_ee_return_cart' );

// also filter the empty cart message:

function my_ee_cart_is_empty() {
	return 'The cart is empty';
}
add_filter( 'FHEE__EE_Event_Cart_Line_Item_Display_Strategy___empty_msg_row', 'my_ee_cart_is_empty' );
