Add External TinyMCE Plugins

Where additional customization is required, custom plugins can be loaded into TinyMCE.

Using a plain text editor, open config/config.js in the extracted Tiny Editors for HCL Connections package.

Note: Use a plain text editor to avoid inserting invalid formatting or symbols into config.js. Do not use a rich text editor such as Microsoft Word for editing configuration files.
Locate the property externalPlugins and modify the array to customize the external plugin configuration using the following resources:
- External Plugins for TinyMCE.
- Create a Plugin for TinyMCE.
- The external plugins customization syntax.
- Connections locations for selectively loading plugins. Tip: If the external plugin array is empty (externalPlugins: [],), no external plugins will be loaded.
```
externalPlugins: [
  {
    name: 'demo',
    url: '/connections/resources/web/tiny.demo/plugins/demo/plugin.min.js',
    on: ['wikis']
  }
],
```
Continue configuring the Tiny Editors integration or continue with the installation.
