We recently enabled webhook notifications for our Statuspage, and would like to get a Google Chat Room notification when incidents are created/updated. I subscribed a chat room using a standard incoming webhook URL, but messages are not being received. The webhook subscription is staying active, so the required 2xx response code is being generated (I tested a bad URL as well, which did get deactivated as expected). Any help as to why the incident notifications are not showing up would be appreciated. Thank you.
