Android app showing and hiding, Open with function not able to make app the default

Friends do you know how could I show the Android clock app? Since I will use FydeOS for my work I think I will end up needing it, also, is there a way to hide Webview beta and Wicked good unarchiver? Right now I have them under a system folder

Also, I can not make sites with WPAs or shortcuts open the links in app instead of the tab by making Open with always open said apps by default

BTW FydeOS for you has virtual desktops? If so what is the way to access them?
