Some question about SIMtrace2

Dear Engineer, I have a few questions regarding simtrace2-cardem-pcsc that I would like to consult with you: （1）、I am using simtrace2-cardem-pcsc to access a remote SIM card by connecting the SIMtrace2 board to a mobile terminal. When I use pcsc_scan, it shows that the card reader has opened the SIM card successfully, and the other end is also connected to the SIMtrace2 board correctly. However, there are no valid APDU commands being printed. Through simtrace2-tool, I only see some reset information. （2）、I would like to connect the SIMTrace2 board to the soft SIM on my computer. Is there any related manual or documentation that could guide me through this process? I would greatly appreciate any advice you can provide when you have time. Thank you very much.
