Nitrokey app opens fullscreen in opensuse Leap 15

This is unwanted. I want it to open only if the key is connected. It shall run when I log in KDE Plasma desktop.
App is 1.3.1 from the opensuse security repos.

What the app should do: it should stay in the tray until needed.
What it does: every user instance it pops up fullscreen. Then I have to iconize it. It is not a big deal to understand each other. But it is annoying.
Any settings I could try?

Try scripts like this:

Maybe you can find some other solutions on the web. There is no “startup minimized” config option in the nitrokey app itself.

While this is true we are working on it.
