also, that plugin should be installed in the authoring tool by default...
sorry for this i am not noticed this
it's a 'core plugin'
all of which are downloaded automatically when you install the authoring tool
any command for view core plugins in it
it says in the link above
If you want to view the framework plugins that are installed in your authoring tool instance, head to Plugin management (found in the top menu). Here, you can view the details of any installed plugins, enable or disable them for use in other courses, and check for any available updates.
