Ayush, we're currently adding the ability to track the schema that a
snapshot was current when a snapshot was written. Until then, you'll get
the table's current schema instead.

I think there's also a PR that adds some ability to use iceberg-arrow like
Iceberg generics. I've not had a chance to review it yet, but that should
help you see what you'd need to do.
