In this Added notice tab, we can customize all the style options for the notice message that appears after you add the product to the cart.
Text to show: set the text to show when a product is added to the cart.
Text alignment: left or center
Text style: choose among the Heading titles or a simple paragraph style.
Notice colors: set the default and background color of the notice message.
Notice icon: choose if you want to show the default icon (a check mark symbol, see below), upload a custom one, or not show any icon at all.
Border radius: finally, you can set the border radius of the four message corners.
Below an example of the notice message with the default icon and a 30px border radius set for the top-left corner.
