PS4 Version is Slow need Ps5 one

Hi I have a PS5 and I recived a PS4 beta code I have played on the PS4 version and it’s very poor. I have a PS5 and I would like a code for that platform as the PS4 version is very slow and poor and I am not used to the gameplay at all. I would appreciate it if I received the correct code. I am happy to provide any proof whatsoever but overall the PS4 version is poor. I need a ps5 code when I play on PS5.
