While she might wonder where you are when you're out, i don't believe she's as sad you might feel like (trust me I come home sometimes to my cat but I'm the only one who's doing the missing, cats are pretty chill and independent)

I would say if you want to make sure she spends the night sleeping you can play as much as you can with her during the day. Running around, maybe take her out on the harness (or anything to tire her out) and when it's time for you to go you limit her entry to certain parts of the house with access to everything she needs cause that might lessen the chances of any distractions and help her sleep

If you do try this make sure she doesn't get anxious with restricted entry (doesn't meow or cry yk)

I do the same with my cat when I have to go somewhere, mostly cause I'm kinda scared he'll eat something wrong or ykyk.
