I create a web application via webapp-manager, it is displayed in the KDE Plasma application menu.
Open webapp-manager, select the application, click "Edit", change the name, save. In the KDE Plasma application menu, the name does not change.
Although judging by the menu editor and the file itself, it should have changed to something else, but this does not happen.
Although if I start making the menu in the editor by hand, it will change.
