The widget is normally displayed at the bottom of your store, and the icon can be changed to any image.

You can also switch to the Display Only Icon mode to save more space.

You can change the widget settings from the theme customization page, and by toggling the "Display Only Icon" checkbox, you can hide everything except for the icon when the widget is minimized.

This will save more space on your screen and potentially avoid overlapping with other components or pop up banners.

By uploading an image from the form, you can switch the icon image to what ever you want.

You can also adjust margin and color of the widget.
