For teams who use something other than slack/discord for communication, allow inputting a webhook URL that just sends a request in a predefined format, (A POST request with a string body would be sufficient, but json with more detail could also be used) that allows teams to define their own handler. I feel like a lot of teams can handle listening for this, and it would allow teams to send the messages to arbitrary platforms.
