Her entire world is new and scary to her right now. Give her 2 or 3 days to just chill out in her cage. Talk to her quietly when ever you are near her cage but don't try to handle her yet.
Put her food in early - before she wakes up so that she will be less upset at having her cage opened and so she will learn that food will always be available when she wakes up hungry.
put a few pieces of fleece with YOUR scent on them in her sleeping pouch. (tuck them in your clothes or pillow case for a few hours to get your scent on them)
She should begin to calm down in a few days - then begin offering treats or petting her through the pouch.
Be patient, take lots of time and let her get to know you and trust you at her own pace.
You have at least 30 days of the quarantine to build her trust in you before you begin introductions.
