I have Ubuntu OS running within VM in VMware Fusion (macOS) so expanding disk from 50 GB to 55 GB is pretty easy. Let's demonstrate the expansion process.
Here is the current list of block devices in my Ubuntu ...

I have 50 GB disk (nvme0n1) having two partitions (nvme0n1p1 and nvme0n1p2) and partition nvme0n1p2 is used as a main operating system disk.
First of all, we have to expand VM's virtual disk in VMware Fusion.

| Disk expansion in VMware Fusion |
Virtual Disk expansion must be done on Power Off VM.
When Virtual Disk is expanded (in our case to 55 GB), we can Power On VM and continue disk expansion within the operating system by following two commands.
sudo growpart /dev/nvme0n1 2
sudo resize2fs /dev/nvme0n1p2
First command expand the partition and second command resize filesystem on that partition.
