In the Last Jedi I recall in the first scene where Snoke's throne room is shown, there are two cloaked figures in the background working on a device. From what I could tell, the figures were remarkably similar in appearance to Jawas.
However, I think this is not the case as the cloaked figures in TLJ seemed to be of taller stature than Jawas. So what are these beings? And why would they be used to service equipment instead of some other First Order technician?
