Subject: [PATCH] feat: extending sidepanel example to include rounded corners
 + new icon

Also adding a fullscreen example.

Also fixed a bug in the example where we were leaving the parent element still on the screen blocking clicks.

Can not be merged until 8.2 goes out with rounded corner support.

 ## Custom elements
 
-This example demonstrates how to use a custom element to change the size and position of the main web chat window.
+This example demonstrates how to use a custom element to change the size and position of the main web chat window. This can be used to move web chat into a sidepanel, have it run in a "fullscreen" mode and more.
 
 It demonstrates:
 
 - How to use a [**view:change**](https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html?to=api-events#viewchange) event handler to show or hide the main web chat window when it is opened or closed.
 - How to use the [**element**](https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html?to=api-configuration#configurationobject) configuration property to specify which custom element to use.
-- How to apply custom animation to the entrance and exit of web chat.
+- How to apply custom animation to the entrance and exit of web chat in a sidebar view.
+- How to embed the web chat in fullscreen mode.
 
 ## Running the Code
 
 ### Running the JavaScript Examples
 
-1. Open the [client/javascript/index.html](client/javascript/index.html) or [client/javascript-animation/index.html](client/javascript-animiation/index.html) file in a web browser. The animation one is a slightly more complex example that demonstrates how to animate that opening or closing of web chat.

The animation one is a slightly more complex example that demonstrates how to animate that opening or closing of web chat as a sidebar.
