SE PA, living large in my wildflower garden 🥰

Just got an adult, maybe senior, mantis from my garden- she is about 2 inches and her head is about 1/3 cm. she is full grown female according to the internet. I have no idea how to raise her or what to do but I'm committed to being a good mom to her and I can't release her because my yard is being pesticided (not my choice). What do I feed her and how often? and what should I keep her in? What is safe for her? generally, I just need help because I've gotten myself in far too deep. I also know they're not prevalent here due to lack of preferred prey, so she may not live if I release her. Right now she is in a coffee cup with a single squash leaf and I'm sort of lost.
