    Thanks Thomas.  Unfortunately I'm not skilled enough to come up with
something from that, also my time is unfortunately limited, and this
further relates to a legal matter.  I searched and searched but no luck
in figuring this out yet.

    Prior to posting here, I did find the below code^1 <#1> on Github,
but still couldn't get that working even for new incoming
notifications.  It looks pretty complicated and I don't see any mention
of Pillow, so maybe some updated code could work better.  I have the
output from dbus-monitor "interface='org.freedesktop.Notifications'"
saved in the journal and right now there is one particular entry that I
need to get decoded.

    I wonder if we could get the code below or something else working?

Thanks,
Chandler
