Failed to remove container disk and reclaim space to main partition

Question

After I removed Boot Camp I found out that the partition space didn't merge back into my main volume, instead it was called "container disk1". There was no option to delete it so I tried to initialize it and I renamed it "boh". Following the answer that was given to this question: How to remove a container disk and reclaim space with main partition?, I ran diskutil list and obtained

    /dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *251.0 GB   disk0

   3:                APFS Volume ⁨Preboot⁩                 302.6 MB   disk2s2
   4:                APFS Volume ⁨Recovery⁩                1.1 GB     disk2s3
   5:                APFS Volume ⁨VM⁩                      3.2 GB     disk2s4
   6:                APFS Volume ⁨Macintosh HD - Dati⁩     115.9 GB   disk2s5

Then diskutil erasevolume free none disk0s3 and it returned:

The target disk is in use by APFS as a Physical Store; use diskutil apfs deleteContainer

so I ran diskutil apfs deleteContainer disk0s3 and now when I type diskutil list this is what I see:

    /dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   2:                 Apple_APFS ⁨Container disk2⁩         200.0 GB   disk0s2
                    (free space)                         50.7 GB    -

/dev/disk2 (synthesized):

   0:      APFS Container Scheme -                      +200.0 GB   disk2

   1:                APFS Volume ⁨Macintosh HD⁩            15.7 GB    disk2s1
   2:              APFS Snapshot ⁨com.apple.os.update-...⁩ 15.7 GB    disk2s1s1
   3:                APFS Volume ⁨Preboot⁩                 302.6 MB   disk2s2
   4:                APFS Volume ⁨Recovery⁩                1.1 GB     disk2s3
   5:                APFS Volume ⁨VM⁩                      3.2 GB     disk2s4
   6:                APFS Volume ⁨Macintosh HD - Dati⁩     115.9 GB   disk2s5

And now I'm scared that I messed it up. The volume doesn't either show up in Disk Utility.

I have a 2016 MacBook Pro 13-inch 4 TBT3, running MacOS Monterey 12.0.1 Thanks everyone in advance
