Why 0 index here? Do we want to handle the case if one nft type has multiple collections like Mint Store?

All the collections are stored in the same path, we just want the ids of them all. Paritioning these into subcollections will take up a lot of gas since you need to borrow each one.

Makes sense!

let catalogEntry = NFTCatalog.getCatalogEntry(collectionIdentifier:collectionKey)!
let path =catalogEntry.collectionData.publicPath
let cap= account.getCapability<&{MetadataViews.ResolverCollection}>(path)

What will not be guaranteed to not exist? I check if the cap is linked on the next line.
