To adjust the widget’s position, open Themes → Settings → Custom CSS and paste the code for the side where your widget currently appears.
Widget on the right: Increase the right value to move it farther left.
.whatsapp-widget-right { right: 10px !important; }
Widget on the left: Increase the left value to move it farther right.
.whatsapp-widget-left { left: 10px !important; }
Change 10px to the distance you need, then save and check the widget on your storefront.
