There is still potential for your little plant. I would improve the media level, it is too below the rim.
This plant has such shallow root mass, so it has to feel the warmth at the root area as well. It seems to take to long to dry out as well since the root zone is so compromised. Ideally using a shallow but wide mouth container is better. The one you have is still okay, but raise that soil level. If you do improve the media, do not water right away. Your plant has no viable roots yet. It needs to grow new ones. For the time being, it will utilize whatever is still stored in its leaves and stem. The best indicator that it is actively growing again is if it show you new leaf formations.
I do not know where you are located...but if your weather permits it, bring that plant out in a part sun area, so it can acclimate to outdoor levels and temperatures. The more light and warmth it can get, the faster growth improvement.
This is one of my cuttings before, I use a shallow but wide mouth container and as you can see, media is very gritty, since I leave them outdoors year round, rain or shine.:
I finally got chicken grit, so I just improved the top dressing later on:
