Welcome to HC & congrats on you new ham

Her behaviour is normal for a new ham, it can take them a few days to settle in & gain confidence.
Her house isn't really suitable though, plastic isn't good & the house is quite transparent so it won't be dark in there.
I would provide her with a cardboard box for now, no base & a hole cut out for a door, or some large bendy bridges to go under & plenty of deep substrate & a nice pile of shredded plain white toilet tissue to make a nest.
If she has some nice hideouts she will feel a lot safer & probably begin to feel confident with you much quicker.
