Topic closed, problem solved. I have contacted the app developer and the app is not being developed further. The phone is original. Checked on many websites and after contacting Samsung support. However, I got scared that the phone is refurbished.
You can't have. That model was just released on the 1st February of this year. So your phone can't be the S23 series, six years would more like have been a S8 or S10 model.
