Oh the one with _ ☐ X on the bar? The more detailed/unique ones are typically designed most easily to be used in cutscenes.
If you want to use them in regular gameplay you'd have to copy them to the overlay and it's more advanced/a bit hard to explain. I'd recommend joining the GB Studio discord if you can.
