An unknown process related to Preview

I launch Preview and search for all processes associated with it in Activity Monitor. In addition to a few regular processes, I see QLPreviewGenerationExtension (Finder).

Is this normal? I have only seen it on an M1 MacBook Pro running Monterey. Not seeing it on Intel Macs. Has anyone else seen this process? It's not consuming much CPU time or RAM, but I have never seen it before. It does not matter if Preview keeps an open file or not...

QL stands for QuickLook, so this is a process relating to QuickLook previews in the Finder, not to Preview.app.

This is an entirely 'normal' MacOS process.
