Optionalentity(Required) Entity pivots to group by; count/constraints depend on finder.
Optionalfinder(Required) adAnalytics finder. See LinkedInAdsFinder.
Optionalmetrics(Optional) LinkedIn metric names for the report. Open vocabulary (not an enum): the valid set is large (~100) and evolves with the LinkedIn adAnalytics API, so values are passed through verbatim. If empty, a pivot-safe default core set is ingested: impressions, clicks, costInLocalCurrency, externalWebsiteConversions (valid for every pivot). Ignored for attributedRevenueMetrics (always returns the full RevenueAttributionMetrics struct).
Optionaltime(Optional) Time aggregation. Defaults to DAILY when unspecified. Used by analytics/statistics; ignored for attributedRevenueMetrics.
User-defined custom report for the LinkedIn Ads connector. The destination table name comes from the enclosing TableSpec.destination_table, the start date from the enclosing LinkedInAdsOptions.sync_start_date, and the account it runs against from the source schema (namespace) -- none are repeated here.
