Minimize to tray ubuntu 16.04 LTS

[yuliym]

I have added icq to autolaunch, but how I can make minimize to tray on boot?
for example:
Telegram: Telegram -startintray
Viber: viber StartMinimized

Thanks.

I think, I found a solution to autostart ICQ in tray. I writing a script (minimized_ICQ.sh) that closes ICQ after 5 second delay, and this cronjob launches it as well as needed:
@reboot sleep 120 && export DISPLAY=:0 && sh "/path/to/minimized_ICQ.sh" >/dev/null 2>&1
Script contents:
#!/bin/bash
/path/to/ICQ/icq & sleep 5s && wmctrl -c "ICQ"
To execute the script, you need only wmctrl to be installed.
