Beardy help

Hello Reddit gods, I thought I would reach out to the experts here.

I’m lizard sitting for my best friend! She has a 7 year old female bearded dragon!
I’ve been sitting since Sunday and im having some feeding worries about her. She won’t eat and kinda sleeping all day and barely moving. I understand that I’m not her owner so she’s not cool with me. But I’ve been trying to get her to eat since Monday and no luck. She has her heat lamp and a heater so I know she’s warm, she typically eats around 4-10 worms. So I was going to try some greens for her! Any suggestions or advice will help! I’m worried since I’ve been out of my lizard game for many years. Thank you!!
