   +1 it feels like here

   iceberg-python/pyiceberg/table/__init__.py

   Lines 1552 to 1560 in c5c0993

   	def to_polars(self) -> pl.LazyFrame:
   	"""Lazily read from this Apache Iceberg table.
   	Returns:
   	pl.LazyFrame: Unmaterialized Polars LazyFrame created from the Iceberg table
   	"""
   	import polars as pl
   	return pl.scan_iceberg(self)

   storage options should default to self.io.properties

   Ah actually it can't just be self.io.properties because some of those non-IO properties conflict with storage properties and you might end up with

   ValueError: unsupported: cannot combine token with default-key in storage_options
