Where to set $XDG_DATA_DIRS so that ilia sees it?

[brianalexander]

Using the latest install for Regolith for Ubuntu 24.04, $HOME/.local/share is not a default in $XDG_DATA_DIRS. Updating $XDG_DATA_DIRS in ~/.profile as recommended in some places does not appear to update the path in time for ilia to detect my desktop files.

Only after using sudo desktop-files-install to install the desktop file to /usr/share/applications, does it show up in the launcher. This is a little clunky as I have to sudo it.

Where should I update the path for $XDG_DATA_DIRS so that it'll be set in time for ilia?

Thanks!
