How to (unobstrosive) highlight a new function in the checkout-process?

Hi,

i am currently working on a new feature in the checkout-process of a B2B-shop.

Our projectmanager now wants to label this new function, so that our customers can see, that this function is new.

The section looks like this:

(and there are similar sections before and after this)

The highlighting should be somewhere near the “Lorem Ipsum”-Tab.
Currently i have a total blackout how and where to place what kind of indicator. ¯(º_o)/¯

Also couldn’t find any examples how to best label new functions somewhere in a online-shop.

Any Ideas?

Thx

Don’t make it to hard for yourself mate, maybe something like this?
