Pulled for Citlali at a low AR

I accidentally 10 pulled and got her. I am AR24 as new player and I am still at liyue so I don't know what to do and how to upgrade her.

I don't wanna spoil natlan for myself as I wanna progress through the map with the story missions and not just hop around.

Is it a good idea to leave her for when I do visit natlan or is she really REALLY good to the point where she will help me as a low AR?

If I do have to keep her then how should I upgrade her?
