Widget Cart Icon appearance customization

I want to display the shopping cart icon instead of the word Cart, However, I don’t see the tab options (General/Layout/Style) as per this https://docs.themeisle.com/article/1233-cart-icon#:~:text=When%20you%20click%20on%20the,that%20works%20as%20a%20slider. “how to” instruction. I can’t see if this is a difference between free/pro either. Could you please advise.
