How do I solve this Tablet code?

I have the following puzzle I am trying to solve from the online idle game structure idle.

Previously, I had different types of puzzles in which I had lists of letter pairs to arrange, for example : AB, DC, CA -> DCAB. I thought this might be a similar type of puzzle, but I’m not really sure how to approach solving it. As far as I know, based on how the previous puzzles were done, the answer should be a string of letters with length 5.
