Configure the compiler path (Clang) on visual Studio Code (for mac OS)

Question

I'm completely new on C++ and I want to use this language on a MacOS with Visual Studio Code editor. I try to configure the Clang compiler on Visual Studio Code as described on this link https://code.visualstudio.com/docs/cpp/config-clang-mac.

However, when I try to do so, configuring the compiler path doesn't seem to work. Indeed, I have two issues:

1. In the Command Palette, it is asked to chose "Edit Configurations" from the list of suggestions. I don't find this suggestion. I, then, decided to click on "C/C++: Edit configurations (JSON)"
2. When I click on it, an error message appears on the lower-right telling me that C-Cpp.ConfigurationEditJson not found.

I have a hard time figuring out what I can do. Can someone enlighten me please? Thanks!
