two questions regarding woocommerce

Hi

I’m doing the final test on my page (using MayaShop). Now, how can I delete or set the ‘billing phone nr.’ to ‘not required’ ?

And where can I change the ‘width’ of the ribbon after clicking on the shopping cart (you will see the complete order and it is too small).

many thanks
