I recently converted NLSQLTableQueryEngine to workflows but it's not showing up on Arize Pheonix properly.

Hi, I recently asked a question regarding the NLSQLTableQueryEngine (https://docs.llamaindex.ai/en/stable/api_reference/query_engine/NL_SQL_table/) and how can I implement the row retrieval part in this notebook (https://docs.llamaindex.ai/en/stable/examples/pipeline/query_pipeline_sql/#2-advanced-capability-2-text-to-sql-with-query-time-row-retrieval-along-with-table-retrieval) but after converting it to workflows instead, and why it is not showing up on Arize Pheonix properly. Anyway, I have made a new class called NLSQLTableRowQueryEngine that inherits from NLSQLTableQueryEngine and a NLSQLRowRetriever that inherits from NLSQLRetriever with small changes to implement the up-mentioned technique in the notebook. I wanted to know what the process is if I wanted to contribute these changes to code base?
