How do I properly resize my LVM partitions when it is inside LUKS?

Do I have to boot in a USB to do it or can it be done while the crypt is open/being used? I need to resize my root partition.

Literally the first result when you Google "lvm luks resize"

Here's a fairly detailed article about it.
You need to provide more info...
You want to resize a logical volume? Growing or shrinking? Is it lvm on luks or luks on lvm?
- @atzanteol LVM is inside LUKS. For some reason, resizing stops even though I unmounted the partition it is still being marked as "active". I disabled my SDDM and everything, rebooted, and still couldn't do it.
  my reaction was "well... maybe there's something else holding this, LUKS maybe?"
  
  What are you resizing though? The luks partition? a logical volume in lvm?
  What command did you run that gave that error? What is it you're trying to do?

Try this.
Haven't used LVM in a while, so I can't offer much insight there other than consider taking a backup of anything important.
- It never occurred to me to attempt such a thing. I'd first try on a throwaway VM and virtual disk I guess. But resizing is already sort of a bad vibe. I'm trying to move towards being able to do full reinstalls more smoothly. That's still a work in progress though.
