🎤 Pitch

A function that would send a message to a specific channel in a specific slack organization via webhook.

Some use cases:

• Manual communication via function with the slack organization (Custom Announcements, for example)
• Sending appwrite project stats either manually or via cron task
• Sending information from 3rd party APIs
