How to get VS code to work with unreal engine

Hi all,
i’m trying to set up visual studio code to work with ue4 4.19. I chose VS code as editor in the engine preferences, i downloaded both c# and c++ extensions for VS, but it can’t open up the include in the header files. VS code says to set up include path to let intellisense know where are the required .h files. I wrote some lines in c_cpp_properties.json with the source folder of the engine, but still i’m missing the compileCommands string who requires a .json file that i don’t know
Thanks for your attention
