Assist AI popup menu visible on all popups of all plugins

Hi @gradusnikov ,
first of all great work!

Seems there is an issue with the config of the popup menu for Assist AI. I can see it on all popup menus of all views from most of standard and custom plugins. As far as I know this


As far as I know it can be customized, but I don't know how it looks in e4 fragment.xmi
In e3 extension I think it was this (org.eclipse.ui.menus)

This can be fixed by adding a menu visibility handler that checks if the active editor is an instance of ITextEditor (IIRC).
