How to create a React app directly in the current folder

I know I've done it before but I can't seem to find the answer anywhere. I want to run create-react-app without creating a whole other folder within the folder I'm already in. I believe it is just an additional flag appended to the command.

You can create a new React app in the current directory by writing . instead of a project name.

create-react-app .
