Can I transfer my custom made characters (2K20)?

I have a PS4 and played 2K20 on it years ago when it was latest version. I cloud-synced my game saves.

Recently bought PS5 pro and installed the game on the new console, downloaded my saved files, but I don't see any of the custom superstars I had created. I thought they will sync with the cloud save, but apparently not. Can I somehow extract them from the PS4 and use them on my new console?

Thanks
