Local(pve) not using all of the storage available in LVM partition it is in

I am using proxmox virtual environment 7.0-8
My machine is named pve, so the corresponding namings below-

The issue I am describing started after I cloned my proxmox HD from a 250 GB HD to a new 500 GB HD.

Originally, with the 250 GB HD, the default local(pve) storage (resides in /var/lib/vz as shown in datacenter>storage) used all the disk space that was available under the LVM partition as shown in pve>Disks> /dev/sdNn which was about 229 GB.
After the clone, my /dev/sdNn partition was showing the same old size of 229 GB, which I was able to extend to use all remaining space - so it is now at 499 GB.

The issue now is that my new local(pve) storage still shows only 229 GB of space allocated to it although both Disks>dev/sdNn and Disks>LVM>pve show 499 GB allocated.

The whole intent for my clone was to make the additional space available to local(pve) so that I could spin up some more VMs and make regular backups of some. Is there a way to achieve this without having to reinstall proxmox? I really want to avoid a reinstall because I have so many custom configurations including SMB share, FTP transfer, additional HDDs shared with SMB share on a Ubuntu VM etc.

Any help will be highly appreciated. Thank you!!

Did you also extend the VG and LV that is ontop on your LVM-Thin?

I have added more clarification to my original post to help explain this. Under Disks>LVM my pve>/dev/sdNn does show 499 GB allocated. However, the storage shows only 229 GB available. Even if I try to add another LVM under data-center, it does not show me the remaining space available to add.

They both show 465 GB available
root@pve:~# pvs
PV VG Fmt Attr PSize PFree
/dev/sdc3 pve lvm2 a-- <465.26g 0
root@pve:~# vgs
VG #PV #LV #SN Attr VSize VFree
pve 1 2 0 wz--n- <465.26g 0

I also realize what's shown under Disks in pve GUI does not match what lsblk shows (which is 499.57 GB)
root@pve:~# lsblk
sdc 8:32 0 465.8G 0 disk
├─sdc1 8:33 0 1007.5K 0 part
├─sdc2 8:34 0 512M 0 part /boot/efi
└─sdc3 8:35 0 465.3G 0 part
├─pve-swap 253:0 0 8G 0 lvm [SWAP]
└─pve-root 253:1 0 457.3G 0 lvm /

Can you post the result of:
cat /etc/pve/storage.cfg

Not sure if this is relevent, but I have two other hard drives for additional storage added as Directory. I see the local storage under /var/lib/viz is also a Directory type. The former two are showing up here-
dir: DIR01
path /mnt/pve/DIR01
content rootdir,snippets,vztmpl,iso,images,backup
is_mountpoint 1
nodes pve
shared 1

dir: Backups
path /mnt/pve/Backups
content rootdir,snippets,iso,vztmpl,images,backup
is_mountpoint 1
nodes pve
shared 1
