Show Widget Cart in the checkout pages

Hello Guys!

I have a question about the widget cart:

How do I show the widget cart even in the checkout pages?

I tried to copy the file “class-wc-widget-cart.php” my child theme and I changed the piece of code that you can see below, but without success.

I’m sure there’s a mistake, but I have a basic knowledge of PHP so I need your help.

Thanks in advance!

Fabio.

public function widget( $args, $instance ) {
		if ( apply_filters( 'woocommerce_widget_cart_is_hidden', is_cart() ) ) {
			return;
		}
