There is an issue in Garuda LXQT-Kwin version that there is no option to add hidden Network. The option is given but it won't work. This problem is with only LXQT-Kwin version only. I have tried 2 more version i.e dragonized and multimedia version, there is no such problem with hidden Network. Please fix this issue.
