I think you need to buy the ouija pointer from the shop.
For me she jump scared me at around 3:30.
Although it didn't happen the following night so maybe it's luck based.🤷
If you get any more info, please let me know because I just got jump scared again at a different time after 12:00 (twice that night because she literally ran across) and tried using the board when she appeared but can't seem to interact with her (not sure what I'm missing).
Yes I got the board and the pointer.
