Conversation search API doesn't seem to be returning the expected data. Hello, I have a user with conversations initiated by admins in our UI (with no user responses yet) as well as user-initiated conversations created via the Intercom API. When I query the individual conversations, the user's contact ID is associated with each conversation, as I would expect. When I query the `conversations/search` endpoint with a filter of `contact_ids = user_contact_id`, though, the only conversations returned are the ones initiated by the user. Is that by design? I would expect that search for a conversation by contact_id would return ALL conversations that the user is associated with. If I'm going about this the wrong way or more detail is needed, please let me know. Thanks.
