No shortcuts on homescreen after installing packages

[jojuma]

Hello,

as the title says, I get no shortcuts on my homescreen after installing packages via 

Code:

sudo apk add <package>

E.g. in "Software" -> "Installed" the Image Viewer is listed. There's no shortcut either, though preinstalled. If I click on "Launch", nothing happens. But I can launch it from the terminal.
To maybe get a shortcut for the Image Viewer, I uninstalled and reinstalled it. By installing a package, a shortcut should be set, but again, there's none.
Same for each package I try to install. What am I doing wrong here?

Thanks!
