Order Refund credited to amazon pay balance.What to do?

Hey folks,
I cancelled an order and got a notification saying the refund was credited to my Amazon Pay balance instead of my bank/card.
Just wanted to check — what does that actually mean? Can I use this money for anything outside Amazon (like UPI, fuel, etc.) or is it locked within Amazon?
Also, any way to transfer it back to my bank account?

TIA! :folded_hands:
