Playstation 5 and Razer Blackwidow v4 75 - pause not working to bring up PS quick menu

No idea why, but pause button doesn’t work. Pressing FN + INS button which should result in Pause being pressed does nothing. While testing inputs on Windows, it works correctly. Any idea what could be wrong? Other random cheap logitech keyboard with FN combination works just fine connected in the same port, but on razer kb menu doesn’t show up.I even tried to save custom config to onboard memory and replaced insert with pause. Even without FN being involved, it doesn’t work. For some reason Pause on razer kb doesn’t behave like playstation is expecting it to. Any idea if this could be fixed at some point? It would be great to have fully functional keyboard on ps for games that supports it. Can anything be done?
