Cannot send evolution to tray via window ID or Title

[SubSonicSoftware]

Unable to use window id or title to send evolution to tray using kdocker & evolution from standard repo installed via synaptic

In addition to trying to launch evolution minimized to the tray via:

#QT_QPA_PLATFORM=xcb kdocker -i /usr/share/icons/hicolor/scalable/apps/evolution.svg /usr/bin/evolution -d 15

I've also tried to reproduce I've followed steps outlined in issue 42:
#42

Specifically:
#42 (comment)
...which does nothing
and
#42 (comment)
...which reports an invalid window id error

I also tried just -n 'Mail — Evolution' too but it reported no matching window found in 5 seconds' error

I had hoped these would work like the following script works fine with merkuro-calendar:

#!/bin/bash
sleep 15
QT_QPA_PLATFORM=xcb kdocker -i /usr/share/icons/hicolor/128x128/apps/org.kde.merkuro.calendar.png /usr/bin/merkuro-calendar

• OS: Ubuntu 25.10
• KDocker version: 5.4-2
• Installation method: distro repo

Thank you in advance.
