I have the watcher as below but I would like to pass the value of the "message" field to the alert message to Slack. Can someone please help? I have my watch syntax as below:

"text": "user minhhungvn107 attempted to execute {{ctx.input.search.request.body.query.bool.must.match.message}} command as root" ---\> this might not make sense at all since I dont have any experience with json but hopefully someone can help me understand how to do this and point me to the right direction of where I need to start to be able to write watches properly

Take a look at the [examples repository](https://github.com/elastic/examples/tree/master/Alerting/Sample%20Watches), which contains a fair share of example watches. For example the `errors_in_logs` one is doing almost what you would like to do.

Side note: You can only access the response from a search, not the request itself.
