How to use integratedTerminal in launch.json for C++ in Visual Studio Code?

I am trying Visual Studio Code for debugging C++ code. I would like the debugger to use the integrated terminal for showing the STDOUT and reading from the STDIN. Currently it opens an external terminal.

I tried putting "console": "integratedTerminal" in launch.json but I get the parsing error: Property console is not allowed.

How can I achieve the behaviour I described?

EDIT: this is my launch.json file

}
