## Use Case Examples
### 1 Button that opens widget
Webmaster wants to create a call to action button on their site that says "Learn More". When a visitor clicks that button, it opens the widget and starts a session. (ideally send a message like: "Hi, I'm interested in this thing.")

### 2 Track events like:
- Chat Session started
- Message sent
The end goal is understanding that a chat session occured in the same web session as a purchase or other "conversion" event, whatever that may be.

### 3 Check if Agents are available and Business is open, then show or hide widget:
- On load, set widget as hidden
- Call JS API methods with conditions
- e.g.
- if 'getAvailableAgentsCount' >0, AND
- 'isBusinessOpen', is "true", THEN
- widget(show), ELSE
- END If
