Where to check debug log?

Sorry about this stupid question. I have googled a lot. But I don't find anywhere to mention where to check my opencore debug log.

I have read https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/debug.html page and I have debug enabled. But it doesn't mention where to check log either.

I tried `dmesg`, but it doesn't have what I am looking for.

Thanks a lot.
