Since I am running into this same issue on Sway, *even though* I added
that line to my Zsh profile, I don't think the user config route is the
right one to recommend.
Editing environment variables certainly *seems* easy, but I consider
myself fairly adept at Linux and I could not tell you in what order they
are loaded, and clearly it matters, since j4-dmenu-desktop gets the
wrong variables when launched from Sway, but the right ones when
launched from a terminal.  Even though Sway was also run from a
terminal, via dbus-run-session.
So clearly there are a lot of moving parts, and a regular user who just
wants desktop apps to work should not be expected to manually edit these
files.
