Post notifications and use channel, message and user context in operational workflows.

Available actions

• Add Reaction to Message
• Send Message To A User
• Send Message To Multiple Users
• Send Message To A Channel
• Request Approval from A User

• New Message Posted to Channel
• New Direct Message
• New Mention in Channel
• New Mention in Direct Message
