See the system log during a OS upgrade

I'm currently upgrading an older Macbook Air from Catalina to Sonoma, When going through a Fedora upgrade, I can press

to see the log of what's currently going on. I assume macOS has a similar log, and I'm curious if it's possible to see it during an OS upgrade. I've been looking at progress bars for several hours and it would be nice to get some confirmation things are happening, and it's not in an infinite loop!
