Geese rarely eat worms. She does need some chick grit to eat anything other than her chick starter. Try taking her outside in some nice yummy grass. It needs to be soft grass thin blades not thick, but even goslings are foragers and eating some grass and getting some fresh air an sunshine might help her get started on her feed. Just keep an eye on her and not let her get chilled. Or over heated if it very warm where you are. How old and how is her brooder set up?
You can also cut her up very small some soft grasses and try her inside her brooder if it's still cold where you are.
