Setup data partion on SSD drive

[mahesh]

I have installed ubuntu server 22.04 and ubuntu desktop on a Mac mini from 2012.
I did accept the default partition suggestions and ended up with a 100 GB root partition. However the SSD drive is 1000 GB and I would like to use the rest of the
drive to store my data EG. Nextclode shared files.

Below is my current partitions.

  └─ubuntu--vg-ubuntu--lv ext4       100G /I have Ubuntu desktop installed so I can either use the terminal or the drive tool in the desktop utilities.
I do hope for some tips or maybe even guidelines how to proceed.
