[GuruprasadHebbar]

Hi I want to add "Source dialog" plugin,

I have downloaded the plugin but where i need to keep here to reflect the same.

i added the config as below
alloyEditorConfig : {extraPlugins: AlloyEditor.Core.ATTRS.extraPlugins.value + ',sourcedialog',toolbars:alloyToolBar},

But i am getting below error
Uncaught Error: [CKEDITOR.resourceManager.load] Resource name "dialog" was not found at "file:///C:/Users/sesa407391/Downloads/alloyeditor-react-component-master/dist/alloyeditor/plugins/dialog/plugin.js?t=H8DA".
