Is it possible to start trojita in tray ?
I use lxqt desktop

i tried with "kstart --skiptaskbar --iconify trojita " without success

What have you tried so far?

define "success"? does the app start ?

if the app window doesn't appear does it show in ksysguard as running?

I wonder if the iconify option is broken, doesn't seem to work in my testing though I found no bug report on bugs.kde.org
