The field FLOW.id maps to EVENT.flow_id. You can used this relation to related EVENT.flow_message_id but from there you're left with an empty id that doesn't relate to any Flow Message metrics. Klaviyo API provides that feature and I would love to see flow messages attributed to each flow

these are the features needed:

{
    "data": {
        "type": "flow-message",
        "id": "RLhGh4",
        "attributes": {
            "name": "Email #1 - No Discount",
            "channel": "Email",
            "content": {
                "subject": "Still have your eye on it?",
                "preview_text": "Don’t worry - we’ve saved your cart.",
                "from_email": "T*****@teakandtable.com",
                "from_name": "Teak + Table Outdoor"
            },
            "created": "2022-10-03T18:42:01+00:00",
            "updated": "2023-03-17T14:13:54+00:00"
        },
        "links": {
            "self": "https://a.klaviyo.com/api/flow-messages/RLhGh4/"
        }
    }
}
