systemd xdg-desktop-autostart.target does not have wallet unlocked

[Barry Scott]

I have been trying to update by KDE environment on Fedora 34 to
you the new systemd startup of KDE.

I have found that autostart scripts are not run as they used to be.

The suggestion, that I really like, is to use systemd user services to
do the autostart actions.

The one I'm trying to make work is to add keys with ssh-add.

The problem I am seeing is that I get a prompt for the password
of the wallet.

I'm guessing that the wallet has not been unlocked before the
xdg-desktop-autostart.target is started.
Does this make sense?

I have tried to experiments to confirm this:
1) "systemd --user start ssh-add" manually after login
2) add ExecStartPre=sleep 5

in both cases I do not get a prompt for the wallet password
and the keys are successfully added.

$ cat .config/systemd/user/ssh-add.service
