Way to Remove from Cart/Checkout Page? Cart Icon?

I noticed that once a student clicks BUY NOW button and they get redirected to the Checkout page, there’s NO way for them to remove it from the cart or go back to the cart to remove it.

Shouldn’t there be a way to just X it out if they added a specific course by mistake? If a course creator has multiple courses and they are enrolling in several and for whatever reason they added one by mistake and wants to remove it, being able to is a MUST.
