Beat Mix - Issues starting off the Project

Hey there everyone!

It’s my first time attempting to get off the Codecademy code editor. On the Beat Mix project,
https://www.codecademy.com/paths/create-a-back-end-app-with-javascript/tracks/bapi-javascript-arrays-loops-and-iterators/modules/project-beat-mix/informationals/bapi-p2-beat-mix

I’m prompted to:

“Once you have the project downloaded, open the root project directory in your terminal.”

Is this asking me to open the project on Windows’ terminal, Visual Studio or Visual Studio Code’s terminal?
If it’s one or the other, I’d like to know how to open the project on Windows’ terminal!
Going on VSCode, I went to the Beat Mix project folder, and followed the commands, “npm install” but I got an error: “found 1 low severity vulnerability”, “npm run start”. I got it right. My second question is: should I ask it to fix the low severity vulnerability?

Thank you!!
