Tropicals & Tender Perennials: Need help with my H. obscura cutting, 1 by nightowl2

I bought a H. obscura cutting a couple of months ago. It was lovely and healthy. I put it in a ziploc bag and it grew some nice roots so I potted it up and placed it on my heat mat with all the other new cuttings. It started to wilt. I thought it needed more humidity so I put a bag over top of it. It got worse and started dropping its leaves. I took it out of the pot and found that most of the stems had rotted. I cut the rotted parts off and put it back in a ziploc bag. It seems to have recovered and is starting to put out a new root.

I’m not sure how to proceed. I don’t have much of the cutting left and I really don’t want to lose it. I read on one of the threads that they rot easily. I’m wondering if I should put some sphagnum moss in a pot and anchor the cutting on the top with a bit of moss over the root. I understand that moss has antibacterial properties so I thought it might help to keep the cutting from rotting again. I won’t put a bag over top so it will have lots of air circulation. I have some rooting gel that has an antibacterial agent in it. Should I put some of that on it? Or does anyone have any other suggestions?

Here’s what’s left of the cutting.
