Discord webhook setup method should be described in detail

[kumo-rn5s]

I tried to send a message to discord through normal webhook, and i found this.

If trigger definition is missing in argocd-notifications-cm, the message will not be sent and there will be no error in the controller's log, even if I installed triggers from Catalog, and set up annotation according to the documentation,
like on-deployed in notifications.argoproj.io/subscribe.on-deployed.<webhook name>

What I did was to define some triggers and use that trigger in an annotation.

apiVersion: v1
kind: ConfigMap
metadata:
  name: argocd-notifications-cm
data:
  service.webhook.discord_webhook: |
    url: https://discord.com/api/webhooks...
    headers:
    - name: Content-Type
      value: application/json
  trigger.on-deployed: |
    - when: ...
  template.app-deployed: |
    webhook:
      discord_webhook:
        method: POST
        body: |
          {...}

kubectl patch app <application name> -n argocd -p '{"metadata": {"annotations": {"notifications.argoproj.io/subscribe.on-deployed.discord_webhook":""}}}' --type merge

Discord webhook setup method should be described in detail in the v:latest documentation.
