Apps installed via Home Manager are not visible within GNOME

Apps installed via the Home Manager are not visible within GNOME (i.e. when pressing SUPER + A). This is not an issue when installing an app via configuration.nix file – i.e. in such case the app is automatically detected by GNOME.

The only way for GNOME is detect new app installed via the Home Manager is to log out + log in, which is tedious.

I’ve read this github issue and tried some fixes and yet they do not work on NixOS as they seem to target other OSs.

These are my configurations:

  1. configuration.nix
  2. home.nix

I also confirm that XDG_DATA_DIRS env var is set and is pointing to $HOME/.nix-profile/share/applications

update-desktop-database command does not seem to work as well:

$ update-desktop-database

Same error occurs when running it as root.
