Visual Studio Code – 'code' is not recognized as the name of a cmdlet, function, script file, or operable program

I’m doing cs50p and I am using visual studio.
In the first tutorial they are using command "code hello.py" in terminal and it should create a file but I’m getting only errors, saying the powershell doesn’t understand comand "code"
