No context menu inside plugins?

I can’t seem to bring up the general context menu when navigating inside plugins. It seems each plugin creates its own context menu, overriding the general context menu otherwise available in Kodi?

For instance, I have several plugins from TV stations, where you can navigate watch their series and episodes over the internet.

I’m using a custom playercorefactory.xml to add a context menu option to play an item using external player VLC, but this context menu is not available when navigating inside 3rd party plugins? The context menu only seems available when navigating local content.
The only way I’ve found to play 3rd party plugin items (such as episodes from a TV station plugin) is changing the default player in playercorefactory.xml – but I do not want to change my default player globally.

Any ideas how to bring up the Kodi context menu when inside plugins?
