I am making .desktop for teamspeak as their programmers didn't.
It ought to work for everyone and to do so I need to target home folder universaly with EXEC.
So let's pretend program X is in
/home/username/.local/Xthis way works only for me
EDIT: This solved it for EXEC but doesn't apply to the ICON thus I placed it to
/usr/share/icons which is workaround.
