[question] I need a detailed explanation on changing the storage device

I know the title isn't clear enough, so lemme start from the beginning.
In the past 8 years I had (and still have) a 120 GB Corsair SSD. But with certain operations I can tell it's nearing its EOL, so I decided to buy a new SATA-3 SSD. This thime the SSD was 250 GB. So I installed the new SSD, formatted it to XFS with GParted, restored the system from a clonezilla image and despite that I used the option to ignore the destination disk size, I ended up having two partitions - one that equaled 120 GB (with the corresponding occupied space by linux (approx. 25 GB), which is also XFS) and one unallocated which equaled 130-ish GB.
I tried a few different options but every time I restored from the backup, I ended up with the same structure - 120 GB XFS and 130 GB unallocated space.
So, the $1 mil question is: how the hell do I make clonezilla unpack the 25 GB operating system and have the rest of the 225 GB free and useable space?
Here's a sketch of what I had with the new SSD and what I actually want it to be: https://i.imgur.com/QFSwVw4.png

You can choose the option "-k1" here:

Ref: https://clonezilla.org//fine-print-live-doc.php?path=clonezilla-live/doc/02_Restore_disk_image
Or since you have finished the restoring, you can use GParted to resize that partition.
