According to the KaiOS Developer Page there are some predefined action icons which developers can use in their projects (or they can design new icons by themselves).
I'd like to use one of action icons but I don't know how.
On aforementioned page there is no any information how to use them (but there's a guideline how to make the new ones).
How to use the action icons? Has somebody already used them?
Maybe I didn't understand the information and I have to make the icons by myself?
