CentOS

Using VMWare Workstation and installed CentOS Stream 9, I had initially configured storage 20GB but due to usage the filesystem root is full. I defragmented using VMWare but no help, I increased the size of the HDD (NVME) from VMWare but now how to increase the Root Filesystem within the OS, I am helpless and since I have done some serious things within so not willing to take risk.

Can anyone guide me as to how to increase the size of Root Filesystem In my case /dev/mapper/cs-root

Please advise!
