I inherited Eclipse RCP application with Sirius plugin embeded, app was developed around 2020-21, I’m building menus in ApplicationActionBarAdvisor and this code is executed, but when application starts menu is not rendered, there is no error/stacktrace,

I’ve added debug.properties to trace what is going on ui but also did not find anything interesting in additional logs, trying to debug it, but I don’t know where to catch something useful. I’m also creating cool bar and this is visible, also commands like save works (using Ctrl+S), but my custom one was not executed. I feel like I make very basic mistake, because this is my first RCP app. Do I need to define menu in plugin.xml and/or Application.e4xmi or it can be done just in code?
