Icon cart on menu

Hello,

can you help me change icon representing cart which is displayed on menu?

I’ve tried with changing the code in two files:
includes/header-top-bar.php (as I read here: https://hb-themes.com/forum/all/topic/how-to-change-shopping-cart-language-icon-in-header-and-menu/ )
includes/hb-woocommerce.php

Best regards,
Wojtek
