Support to control which messages will be triggered to webhook

[guptag911]

Hi,
It would be great if the user could control which messages will trigger the webhook.
This feature can be extended to the channel level, allowing for the control of this channel or event, where no messages will be triggered on the webhook.

Use case:
My application supports typing events, but even with the debouncing of 10 seconds, these typing events come on my webhook channel, adding unwanted load to the servers.

Let me know your thoughts on the same.
