7) Click Launch icon next to your new Visualforce Page. We recommend keeping the page in a separate browser window, so you can easily access it while you’re in the console.
8) Your Visualforce Page should display your offline chat button. Let’s go online!

9) Go to your Setup window and use the app picker to open Armor Decor Console.

10) Open the Live Agent widget at the bottom of the page and change your status to online. Now you can receive chat requests!

11) Go back to your Visualforce Page. Refresh it. Since you’re online in the console, the button should change to an online button.

Click the chat button to request a chat.

12) If a chat window appears and you get a notification in the console, everything’s working perfectly. Great job! Go ahead and accept the chat request from the console to start your chat (with yourself).

 

Chat as much as you’d like, then end the chat using the End Chat button on either the chat window or the console.
