Fleet C++ run.json

Question

I've just read this question: How to create and configure run.json in the new JetBrains Fleet for C++?

But I can't make it run, I don't know what to add into the run.json:

{
     "configurations": [
         {
             "type": "command",
             "name": "run",
             "dependsOn": [
                 "build"
             ],
             "program": "C:/Users/Khakis/Documents/C++ Learning/<I don't know what to put here>",
         },
         {
             "type": "command",
             "name": "build",
             "program": "C:/msys64/mingw64/bin/g++.exe",
             "args": [
                 "$PROJECT_DIR$/main.cpp",
                 "-std=c++17",
                 "-pthread",
                 "-O2",
                 "-o",
                 "solution"
             ],

         },
     ]
}

Thanks for help. In the C++ Learning I have this:
