Corsair k55 on ps5

So I bought a k55 for my ps5 cause I found out some games support it and figuered i could still play keyboard and mouse on some games when im playing with my freinds on ps5

Tldr in short I plugged my keyboard in to the ps5 the system recognizes its plugged in but I can not use it on anything ive tried the home page youtube nothing works is there something im missing that I need to do to make it work ?
