How to add custom menu to the default Context Menu?

I want to add a customizing menu to the default Context Meun, when I right-click on an object in Hoops Communicator.
And I wanna link the customizing menu to another web page.

Hello @hskwon,

The Communicator public API does not have functions to modify the user interface. Thus, there is not a direct way to add new items to the context menu. That being said, as mentioned in our docs on the topic of User Interface, we do make available the source code to the user interface which can be found in /web_viewer/src/js/web_viewer_ui.js. This could be a good starting point if you would like to develop a UI more suited to your particular requirements.

Thanks,
Tino
