I named the photos in order to follow the steps.
Step 1 is the one that I did the prompt for comfirmation and reset cart which is succesfully executed.
Step_to_be_done is the Appearance>>>Widgets section that is shown on my display, where i tried to add in the Default Sidebar the Widget of Product before cart reset--which i am not completely sure if it is done correctly as it does not show on the checkout site where i would like to implement it.
I was wondering if you might be able to provide some insights or recommendations pertaining to the aforementioned subject.
