How do you add a discount to a Stripe transaction? I'm using the latest version of Wappler and have the datastore items going into the Stripe checkout page fine and it lists all the items. I thought I could just add an item with a negative value and it would reduce the total by that amount but Stripe doesn't like that.
So there must be a way of having a discount as a separate value but I can't see where to add it.
I have a checkout page which just has the Stripe Embedded Checkout in it but there are very few attributes.
Can someone tell me how to do this?
