Show warning banner based on cart events

Hi there,

I noticed there’s a new event hook system for the POS that allows POS extensions to hook into cart events like `pos.cart-update.event.observe`

Is it possible to subscribe to one of these events and show a warning banner and/or block checkout based to notify the operator that an action is required before finishing checkout?

I’m a bit confused on if this is possible outside of your POS extensions’ modal render component.

We want to make sure that operators are completing the action required for some orders based on the products in the cart.
