Resize VM disk - Error: -69743

Hi,

I recently resized the disk of the macOS (Big Sur) VM. (Hypervisor: Proxmox)

Now I want to assign the new space to the apfs container.

I have already tried the following command:

diskutil apfs resizeContainer /dev/disk0s2 0 

Output:

Error: -69743: The new size must be different than the existing size 

Via Disk Utility its also not working: same error.

Any idea?
