"Goto reference" for C++ seems to only work on functions?

[Lukasz]

“Goto reference” (Shift+F12) works perfectly fine for C++ functions, but doesn’t work at all for C++ classes or variables. Can it be fixed somehow?

Classes and variables are currently not or only insufficiently scoped. Hence can’t be specified as “Goto Reference” targets.

Best chance to get a functionality like that is using LSP and LSP-clangd
