Hi guys, I am trying for some time to achieve something with KDE Plasma 5. I am trying to make launcher icon in task manager which will not disappear when that application is opened. So far, I succeed the following (attachments). As you can see, the launcher icon disappears when you launch the application. Do you have an idea how to achieve that? Thanks!
