Which settings can I set to Codeanywhere project config for C++?

Hi there I am currently using Codeanywhere as an on-the-fly IDE for C++, to be able to easily code between different devices. While setting the Codeanywhere environment, I ran into the "Project Config" file (that gear icon beside "Run Project" button), and I havent found nothing on this file's parameters.

I'm wondering if using this I could set compile and run settings (something like Visual Studio Code).

Am I missing an obscure documentation page?

Also could anyone explain those default settings?

Project Config C++ file

    {
      "run": [{
        "default": true,
        "devbox": "cpp_test"
      }]
    }

Thanks!
