hello, how do i merge tables when running increment dedup? my stream creates two tables because of nested structure. main table has _airbyte_unique_key but i don’t see any sensible value to map this to in the second table:

_airbyte_hubspot_companies_hashid STRING 	NULLABLE 	
_airbyte_ab_id STRING 	NULLABLE 	
_airbyte_emitted_at TIMESTAMP 	NULLABLE 	
_airbyte_normalized_at TIMESTAMP 	NULLABLE 	
_airbyte_properties_hashid STRING 	NULLABLE
