I'm trying to start my program with root to another users on machine.

I already tried "runuser"(-l and -u) and "su username", but no way to make it works.

The best try, for now was:

sudo runuser -l username -c "DISPLAY=:0 XDG_CURRENT_DESKTOP=$XDG_CURRENT_DESKTOP program-name"

The program works, without error, but no icon appears :(, somebody have any glue who to make it works?
