How to Delete Unused Assets from Large Dataset - Timeout Error

Hey everybody, can somebody advise me on how to deal with deleting unused assets from a large dataset, my query gives me a timeout error. It works ok for smaller dataset. I would appreciate any help!

*[ _type in ["sanity.imageAsset", "sanity.fileAsset"] && count(*[ references(^._id) ]) == 0 ] [0..99]

Found a way around, just needed to reduce size of batch.. From [0..99] to [0..1]
