What would be the workflow when using such tools like this or Source Trail? I've used cscope once while I'm testing out vim as my main text editor a bit.
Nowadays I'm using the global search feature of vscode for code exploration. Combined with the available language server for each language, it seems to work well enough for me currently.
VSCode has this with Ctrl+Shift+P which I use all the time. Not a big time JetBrains user but I think tapping Shift twice does the same in their IDEs.
