First message in conversation_part_history not available

Hey there,

When using the Intercom API via Fivetran to get conversation_part_history data, we get it in correctly but not the very first message.
The first message creates the conversation and usually comes from a customer or lead. But when getting the full conversation in, the API doesn’t return this very first message for some reason.

This message can be found within conversation_history, but we don’t see why it’s not part of conversation_part_history.

Are we missing something?

Thanks in advance!

Levi
