Bots use the Trigger and Alert functions to deliver messages to identified recipients. These functions are found in the Bots tab as switches when using the List view.
When the Grid view is used, these functions are in columns. 
The Trigger identifies the conditions that define the events and scenarios when a bot message will be sent as an alert. Switching the trigger on will tell the app that a message has been prepared for activation.
Meanwhile, when enabled, the Alert switch allows the bot to send the message as defined by the Trigger. Turning it on sends the prepared message out every time the trigger conditions for it are met.
To send an alert message once a bot's conditions are met, turn on both the Trigger and Alert switches.
