Is it possible to get group change events?
I'd like to send a message whenever someone new joins a group. Ideally, I'd like to do this even if they don't send a message. It looks like there is a message received, like {"jsonrpc": "2.0", "method": "receive", "params": {"envelope": {"source": "+447522178694", "sourceNumber": "+447522178694", "sourceUuid": "948b2509-91c4-465a-a43f-20c34d41112e", "sourceName": "", "sourceDevice": 1, "timestamp": 1649115144499}, "account":"..."}}, but there aren't any other details and I'm not sure if this is for some receipt or the actual group change event. Is there a way to do this?

this would be really helpful in mitigating some of the intense group-related spam that's been going around recently
