Using LADB: "sm partition" does not show any differnce in internal storage

Using LADB (Local ADB Shell App) i tried turning my SD card into expandable internal storage (or adoptable storage, which isnt availabe on my samsung). I am unfortunatly not able to connect my phone to a computer, but it should work the same through the local shell. The command sm partition disk:179,32 private or even sm partition disk:179,32 mixed 50 should expand my current internal storage. The "mixed" option even shows half of the original cards storage as a secondary sd card in my file system, but there is no change in internal storage at all. sm partition disk:179,32 public is not effecitve as well. Maybe it just doesnt show any difference, but i want to be sure that this worked, and if not - why?
