discrepancy between getwindowclassname and search --classname for google chrome

[eduard5557]

Operating System: Kubuntu 26.04 LTS
KDE Plasma Version: 6.6.4
KDE Frameworks Version: 6.24.0
Qt Version: 6.10.2
Kernel Version: 7.0.0-22-generic (64-bit)
Graphics Platform: Wayland

I observed an inconsistency between Firefox and Chrome, not sure if I'm using this correctly or not. I get the window properties using qdbus6 org.kde.KWin /KWin queryWindowInfo

For Firefox

qdbus6 org.kde.KWin /KWin queryWindowInfo
    activities: dd8e24be-9fbf-494d-ba8c-4282f46e7dab
    caption: Mozilla Firefox Private Browsing
    clientMachine: 
    desktopFile: firefox
    desktops: 81d66064-80ba-4bd5-902f-de50f9355729
    ...
    resourceClass: firefox
    resourceName: firefox-bin
    role: 
    ...
    uuid: {1c798dd5-85d7-4d54-b56a-5e8d5084dfe0}

I get the classname from UUID then in reverse I get the same UUID from that classname

kdotool getwindowclassname {1c798dd5-85d7-4d54-b56a-5e8d5084dfe0}
  firefox
kdotool search --classname firefox
  {1c798dd5-85d7-4d54-b56a-5e8d5084dfe0}

**For Chrome **

qdbus6 org.kde.KWin /KWin queryWindowInfo
    activities: dd8e24be-9fbf-494d-ba8c-4282f46e7dab

    resourceName: chrome
    role: 
    ...
    uuid: {76e08c67-680d-4c4a-b4a1-9fde8999dd8b}

I get the classname from UUID then in reverse I don't get the same UUID from the same classname

kdotool getwindowclassname {76e08c67-680d-4c4a-b4a1-9fde8999dd8b}
  google-chrome
kdotool search --classname google-chrome
  <nothing>

I'm not using it correctly or it's a little bug?
Thanks

Sorry that the naming of those options is confusing here (IIUC, they were inherited from xdotool). You need to use --class, which is what getwindowclassname actually returns.
