You can access it just fine. You just don't *understand* it. (Neither
do I.)

If it's a symlink whose name begins with "invocation:" and whose target
is a 32-hex-digit (128-bit) value, like the one shown above, then
you are seeing everything there is to see. I don't know what the 128-bit
number is used for, but that number *is* the data. Of that, I'm certain.
I did a bit of Google searching, and I think this is something called
an "InvocationID".

unicorn:~$ systemctl --user show -p InvocationID at-spi-dbus-bus.service
InvocationID=bfec6466520a4586b8c9205c235ccc92
<https://sleeplessbeastie.eu/2022/07/01/how-to-display-systemd-journal-for-specific-service-since-it-started/>
describes this as "a unique 128-bit ID identifying each runtime cycle
of the unit".
There is also a man page systemd-id128(1) ("man systemd-id128") but it
doesn't describe things in a way I can currently understand. It seems
to reference another page sd-id128(3) which I do not have, but which
I can find online at
<https://manpages.debian.org/bookworm/libsystemd-dev/sd-id128.3.en.html>
... which, OK, that's pretty boring. What I cannot find anywhere is
a basic explanation of *what this ID is used for*.
Maybe it's just a fancy PID? I dunno, it's all very shrouded in mystery.
