VSCode Multiple-Folder Workspace Search references

Going through a project that start to be quite huge, we've got a workspace with 10+ folders.

Into those 10+ folders we have 9 folders that have the same code base in Node.js & the 10th one that is a private NPM package that we build and that all 9 others rely on.

We're trying to make things easier for all the devs to find some other usage of a function they want to explore and for that, we wanted to be able to find some function references / implementations across all the folders of the workspace.

For instance, if I go in one of the folder, in one of the source file :

and I right-click on the authorize method that is custom and implemented into the NPM private package. If I look up for References I'll get results like this :

But those are only the result of the reference of this method into this folder and not into others project that also use this express middleware.

You can see that I also get the result of the dist folder of the NPM package which seems logical but also seems to be the problem that I am facing.

I don't really know what can also be useful so feel free to ask me any kind of content and find attached the workspace configuration :
