How to support this plant?

Some weeks ago I bought some wetsticks and cuttings off an online marketplace and put them in a clear container with sphagnum moss.
I just came home after I let the box open for an hour or so for air circulation and the newest leaf (foreground) and one other leaf lost all its stability. The plant was pretty much exposed to the direct sun sadly.
I potted it in an attempt to save it, I don't know if that was even more stressful.

How would you support the plant to save it?
Should I put it back in a box to maintain high humidity?
Should I remove it and put it to normal humidity in my living room since I already potted it?

I hope you have some suggestions, thanks in advance!
