Hi
I design various bots on Ubot.I am able to sell these developed bots on codecanyon,these are my developed bots,
I doubt it would be allowed.
I don’t know much about ubot but usually this type of app or tool generates messy code.
Also it looks like licenses for it are as standard per user or per team but there does not universal.
I also assume that to edit or update functionality would require access to ubot which would also not be allowed.
