Trying to drop a single participant from an active conference call via the API. I’m hitting PATCH /api/v2/conversations/calls/{conversationId}/participants/{participantId}/communications/{communicationId} with a valid OAuth token, but I keep getting a 404. The conversation ID, participant ID, and communication ID are definitely correct since I grabbed them from the live event stream. Am I missing a specific header or is the endpoint structure different for multi-party calls?
