This already implemented but have the following breaking issues:
Nullable(polygon) if source DB has the Polygon null will throw an error: java.sql.SQLException: Code: 43. DB::Exception: Nested type Polygon cannot be inside Nullable type. (ILLEGAL_TYPE_OF_ARGUMENT) (version 24.7.1.1).
If 1 is fixed manually still data won't get inserted:
java.lang.ClassCastException: class [B cannot be cast to class java.nio.ByteBuffer ([B and java.nio.ByteBuffer are in module java.base of loader 'bootstrap')

3. If 2 is fixed manually still the current implementation tries to store Polygon as HEX in a Clickhouse String, while maybe there's a use case for this, I believe the best way is to store it as Clickhouse Polygon for advance analytics in Clickhouse.
I will fix these issues and PR it today.
