LINE Organic: Add message-level insights (impressions, clicks) by date#1466

I would like to request the addition of message-level data to the LINE Organic connector.

Requested additions:

1. Message-level delivery data

   • request_id (unique identifier for each sent message)
   • message send date/time
   • delivery count per message

2. Message-level interaction statistics

   • impression (opens)
   • uniqueImpression (unique users who opened)
   • click (URL taps)
   • uniqueClick (unique users who clicked)

this was implemented
