Grafana alert to slack only need information

Grafana Alerting
1

I use grafana 9.3.2 and want add short alerts to slack.
Now I created this config:

{{ define "myalert" }}
  [{{.Status}}] {{ .Labels.alertname }}
   {{ range .Labels.SortedPairs }}
    {{if eq .Name "ip"}}  {{ .Name }}: {{ .Value }}  {{end}}  
  {{ end }}
{{ end }}

{{ if gt (len .Alerts.Firing) 0 }}
    {{ len .Alerts.Firing }} firing:
    {{ range .Alerts.Firing }} {{ template "myalert" .}} {{ end }}
{{ end }}
{{ if gt (len .Alerts.Resolved) 0 }}
    {{ len .Alerts.Resolved }} resolved:
    {{ range .Alerts.Resolved }} {{ template "myalert" .}} {{ end }}
{{ end }}

And I had this result:

11 firing:
