Question about Java game process

So, is there a way to add certain Java games that the process is just "java" into the list? Maybe with their window name? Like how KDE Plasma does window rules, it uses a specific name that idk where it gets but it works
For example, WAKFU is the game I'm trying to add, the process is just "java" but with KWin rules it gets another name "com-ankamagames-wakfu-client-WakfuClient"

I tried to add this name to the list but it didn't worked

I also tried using this name from the taskbar and also didn't worked

Another thing, not directly related to Java, but it still related to wakfu, I added a rule to the launcher that only runs in the background like a service, but a lot of their processes didn't stick with the desired nice, look, its the zaapi process
