Which connector?: Gong

Additional details:

We noticed today that our Gong connector is synchronizing private calls (`CALL WHERE IS_PRIVATE = true`).

That poses serious privacy issues for us. We'd like a way to filter those out.

I contact Fivetran support and they said the most we can do currently is to filter out rows from the `CALL` table (which is an `is_private` row). However, the most sensitive and important rows are in the `TRANSCRIPT` table, which has a `call_id` row but no `is_private` row.

More generally, we'd like to exclude anything connected to a private call or through something else connected to a private call. But excluding the transcript rows is the highest priority.

For reference, Airbyte's docs have this: (https://docs.airbyte.com/integrations/sources/gong#private-calls)

> Starting with version 1.1.0, the connector excludes calls marked as private (isPrivate: true in the Gong API) from the calls and extensive calls streams. Because call transcripts is a substream of calls, transcripts for private calls are also excluded. Gong requires this behavior for OAuth app listing approval, and the Gong API does not expose a server-side filter for this field, so the connector applies the filter client-side after fetching records.
