If Progressive Discount is active alongside Side Cart, the reward ladder it manages can be shown directly inside the drawer, on the Progressive Discount slot.
What you get
The slot reads the same reward ladder and cart context Progressive Discount already calculates, so the numbers a shopper sees in the drawer always match what they see everywhere else in the store.

Requirements
Both plugins need to be active, and Progressive Discount needs at least one reward ladder configured for the slot to have anything to show.
What happens without Progressive Discount
If Progressive Discount is not active, or has nothing configured, the slot simply does not render — it fails quietly rather than showing an empty box or an error.
