[FEATURE] Needing to restart gateway and designer after changing/adding icon libraries

I’ve tried it and it is not working. no matter what i try. it never worked.
the best i can get is adding the icon library to the drop list. but icons never get displayed. but the path is working. and i keep getting error in the log

EDIT: It worked finally. the format of the sprite file must be very accurate. make sure to follow this format:
