Once you have a theme saved, you can apply it to a new or existing Widget by selecting it from the dropdown in the Customisation step.
Once selected, the Widget you're currently editing will change to match the customisation options of the theme you have selected.
Once this is done, simply click on NEXT to update/save your Widget.
