Trying to subscribe to conversation events via the Notification API WebSocket using Python.
The connection to wss://api.mypurecloud.com/api/v2/notification/websocket succeeds, but sending the subscribe message returns a 403 Forbidden.
Here is the payload:
{"action":"subscribe","topics":["/queue/54321/inbound"]}
The access token has the conversation:view scope. What am I missing?
