How to confirm settings are loaded in minttyrc / %APPDATA%\wsltty\config?

[dhow]

Is there a way -- say, showing verbose startup log -- to tell that settings have been loaded? I was following #150 to enable Ctrl + C / V for copy and paste so I added CtrlExchangeShift=yes to %APPDATA%\wsltty\config per README.md, however, after restarting wsltty / Windows I'm still not able to use Ctrl + C / V as copy and paste so I start to wonder if my additional config was even loaded.

Thanks!
env: Windows 10, WSL 1, wsl 3.6.4

You can invoke MINTTY_DEBUG=C mintty from a command line.
