Troubleshooting using game controller as pointer/keyboard

Hi. I’m trying out the new Plasma 6.6 feature of using a game controller as a pointer and keyboard, but not having any luck. My controller (an Xbox 360 one) is connected and shows in the Game Controller KCM, but toggling the option to use it as a pointer and keyboard seems to have no effect. I’ve tried in both X11 and Wayland.

Any ideas on how to troubleshoot this, before I open a bug?
