A Couple of days back I installed KDE plasma full on my ubuntu 20.04 machine. But when I was setting up my desktop and installing stuff around. I was unable to find a margin separator widget in the widget panel and was also unable to find it in the discover store too. I know it is given in the pre-installed but not in my case. Can you help me out how to get a margin separator on my pc?
