what is the command to rescan lms library

Hello. Not sure why I have trouble with this - I've used LMS (and before that Slimserver) for 20 years. But, I can't seem to find the command that runs when I do this:

Click on Settings>Click on Rescan under Basic Settings

I'd like to know what the command is that runs when I click "Rescan"

I have set the option to rescan my library every morning at 5 a.m. (Rescan Music Library (v1.0)) under Plugins

I want to set up a cron job to rescan at other hours.

I run LMS on a headless Ubuntu server VERSION="22.04.1 LTS (Jammy Jellyfish)"

Thanks.
