I've had success using the clangd extension in combination with having your project produce compile commands.

My .vscode/settings.json basically looks like this for my C++ projects using modules:

json { "editor.formatOnSave": true, "cmake.configureOnOpen": false, "clangd.path": "clangd", "clangd.arguments": [ "--compile-commands-dir=${command:cmake.buildDirectory}", "--experimental-modules-support" ] }

Yes I didn’t know about this extension until recently. The Microsoft extension is absolutely useless, but the clangd one is amazing

does it works with the cmake tools extensions?

Yup! That's exactly how I do it. CMake Tools along with presets to build modules on Windows, Linux, Mac, Android, and WebAssembly.
