First off, good for you for taking in an older kitty
Given that she's so new, she's still adjusting and needs to find her comfy spot. What did she sleep in/on previously? Cat bed, blanket, or towel, etc.?
I had good luck adding a fleecy cat bed on my daughter's bed. When Pepper was small, she used to walk all over the bed during the night, but the cat bed became her spot once she got used to it. Now she likes to sleep under the covers and will tug at them if she can't get under
We let her in and that usually settles her.
Probably she will settle a bit once she is there longer and figures out where she is comfortable
See what she sleeps on during the day and find a similar item for her to sleep on in your room.
If it continues...I would go for the statue method over food. I give mine a snack right before bed. I don't want them to think that waking me up in the night equals food! Cats are usually good at getting the message if you are consistent.
