Can someone tell me how (if possible) to display a Shopping Cart icon in the top menu header for MOBILE devices?

In regular desktop mode, if someone adds an item to their shopping cart, the Shopping Cart link will display. But in mobile devices, if someone adds an item, there is no icon for them to see and click.

Instead, they have to click the menu (three horizontal lines) and then go to the Shopping Cart. It would be easier if the template would reduce this to one click instead of two.

We have had some customers complain that they couldn't find how to checkout, and we figured out it's because they continue browsing for more items, and then forget how to get back to the Shopping Cart. Having a little icon at the top of the mobile menu would eliminate this issue.

I didn't see if there was any configuration item in the Admin Menu to allow that to display or not.
