API call to drop single participant from conference call

Hey folks,

Trying to kick a specific agent off a conference call via the API without dropping the whole thing. I’m hitting DELETE /api/v2/conversations/voice/participants/{participantId} but getting a 409 Conflict. The docs say to use the transfer body for this, but I’m not sure what the JSON should look like to just disconnect them.

{"error": "Participant cannot be deleted because they are part of a conference."}

Anyone got a working payload for this?
