Thank You so much for approving them😊. I would like to contribute more, can you guide me further on what to do next??

Thanks for updating this version macro, and congratulations on your first microsoft/STL commit! 🎉 😺

As @mnatsuhara mentioned on Discord, the maintainer team is busy with finishing C++20 so our ability to provide guidance is limited at the moment. After briefly looking over our issues list, I think that further PRs to improve #206 could be suitable. Instead of trying to apply _NODISCARD to the entire STL (which would be a ton of work), you can pick just one header (or a small handful) and look for opportunities to apply _NODISCARD following our criteria. #1474 is an excellent example of such a PR.
