I am trying out theia browser (@theia/example-browser 1.2.0) on windows but the main features like “Call Hierarchy”, “Goto Decleration”, “Goto Definition” etc are all greyed out. I gave a try with Java and C, multiple projects but so far have not seen these menus active. (Screenshot attached).
Also tried electron desktop version but there also menus like “View” > “Call Hierarchy”, “Outline” etc do not seem to do any functions.
Any suggestions what could be going wrong?
