Sending WhatsApp interactive message of list type fails when sent with image header - facebook

Question

I am able to send interactive message with "button" type and 3 buttons with image header.
But sending interactive message with "list" type and same image header fails with error:
{
"meta": {
"api_status": "stable",
"version": "2.39.4"
},
"errors": [
{
"code": 1008,
"title": "Required parameter is missing",
"details": "Failed building interactive message. Invalid Header."
}
]
}
Is it possible that "list" interactive messages doesn't support "image" header without stating it in documentation?
Successful "button" interactive payload (image URL changed):

Well, it does state it in the docs. I'm just blind:
Kinda weird though "image" header not supported for "list".
