Trying to kill off a web messaging chat from our internal Node service instead of waiting for the guest to hang up. I’ve verified the token has messaging:close and I’m sending {“conversationId”: “a1b2c3d4-e5f6-7890-abcd-ef1234567890”, “reason”: “backend_timeout”} to POST /api/v2/conversations/messaging/closesession, yet the SDK docs only reference clientAppSdk.closeSession() which is strictly for the desktop widget. Response keeps throwing a 401 Unauthorized even though that same bearer token works perfectly for GET /api/v2/conversations. Not sure where the auth chain breaks.
