What is the equivalent of `--class` in Konsole?

Question

I'm using Wayland + SwayWM. Inside of Sway, I'm using the Konsole terminal. From time to time I would want to open another terminal window in the "launcher" fashion, as in some Sway-compatible launchers such as sway-launcher-desktop.

To make that work, I would need to pass an option of --class to the terminal command, in the Sway config, something like this:

set $menu exec konsole --class=launcher -e sway-launcher-desktop

But I realized that konsole doesn't have a --class option. So my question is what is the equivalent of --class in Konsole? Or is there some other way I can achieve this?

Thanks!
