@Phil n$ , Starting in version 2006, we can configure the Company Portal to also show Configuration Manager apps. In our environment, the version is 2103 and it is support to show the Configuration Manager apps. Based on my understanding, when we click install on the application which is deployed on Configuration Manager. It will do the evaluation and connect to Distribution Points to download the application etc and install the application
So if we want to install the application from configuration Manager, we need to have connection to our Configuration Manager server.
Hope it can help.
