No tray icon when starting Plasma

[simonbcn]

Steps to reproduce

I have enabled "Open Telegram when system starts" and "Open minimized".
But when I enter my desktop (KDE Plasma) there is no tray icon for Telegram although it is running in the background.
Also if I open Telegram (on startup) using the KDE menu and close it, the application terminates.
It only works fine if I open the application manually from the menu (without using the startup option).

Expected behaviour

It should show the icon in the notification bar.

Actual behaviour

It should NOT show the icon in the notification bar.

Operating system

Arch Linux

Version of Telegram Desktop

4.5.6

Installation source

It works well if I add a delay to desktop file:
