Aside from what's already been said, you can try playing with her as well with toys that keep you at a distance from her. E.g. stick with a cord on it and some toy on the end of the cord or something similar.

Try just moving it around in front of her to get her interest, then let it stay still for 5-10s to see if she's interested in hunting it (if she goes flat on the ground, wiggles her butt or her head at it she's preparing to pounce). Don't let her get it easily but let her catch it before the end of playtime.

Some cats will appreciate it more than food, others won't - they each have their preferences.

If she doesn't engage and doesn't seem to be interested in the toy at all, just let her be.
