Likely impacts:
When users select items to delete, you could fade everything else and highlight only the selected items, so their selective attention lands on what they're about to lose.

When someone hovers over a 'skip' button, try making the nearby line explaining your recommendation glow, so it catches their attention as they decide.

When asking users to add money, one option is to request the amount first and load in the other payment details afterwards, so their focus stays on one thing at a time.

When a screen has nothing set up yet, e.g., no filters applied, consider showing a literal arrow pointing at the control to tap, drawing attention straight to it.

If an order is going somewhere far from the user's current location, it may help to show a warning on the payment screen, where their attention already is before paying.

Fading competing elements and highlighting what matters could steer users' selective attention to the key action or message, making it more likely to be noticed.
Revealing one step or detail at a time could help users focus on what matters now, which may make complex flows easier to understand and reduce missed details.
