How to cover more changes from the default Slack integration?

Hello,

We are using the default Slack Integration `send-to-slack` notifier in a YouTrack inCloud instance which was migrated from a Standalone instance. The code is exactly the same as the standard, with the webhook URL customized.

My question: What exactly to we have to do to the `guard` to notify on ALL changes, like added comments, values changed in any field, etc? I can probably work out the `action` side to adjust the payload accordingly but it's unclear exactly how to be notified of all changes and all comments, without having to list individual `isChanged` conditions for each possible field..

Thanks,

Marc
