code analysis c++-20 (and beyond)

[hros]

how can I set the integrated clang-tidy to recognize c++-20?
I tried adding "--std=c++20" to Clang Tidy: Args but that did not make any change (code that compiles correctly without any warnings shows many linter errors)

Our clang-tidy feature currently gets most of its configuration from IntelliSense, so you need to set the cppStandard setting in c_cpp_properties.json or C_Cpp.default.cppStandard.
